450: Get rid of chrono in favor of time r=Kerollmops a=irevoire
We only use `chrono` as a wrapper around `time`, and since there has been an [open CVE on `chrono` for at least 3 months now](https://github.com/chronotope/chrono/pull/632) and the repo seems to be [struggling with maintenance](https://github.com/chronotope/chrono/pull/639), I think we should use `time` directly which is way more active and sufficient for our use case.
EDIT: Actually the CVE status has been known for more than 6 months: https://github.com/chronotope/chrono/issues/602

442: fix phrase search r=curquiza a=MarinPostma
Run the exact match search on 7 words windows instead of only two. This makes false positive very very unlikely, and impossible on phrase query that are less than seven words.

445: allow null values in csv r=Kerollmops a=MarinPostma
This pr allows null values in csv:
- if the field is of type string, then an empty field is considered null (`,,`), anything other is turned into a string (i.e `, ,` is a single whitespace string)
- if the field is of type number, when the trimmed field is empty, we consider the value null (i.e `,,`, `, ,` are both null numbers) otherwise we try to parse the number.

417: Change chunk size to 4MiB to fit more the end user usage r=Kerollmops a=ManyTheFish
Reverts meilisearch/milli#379
We made several indexing tests using different sizes of datasets (5 datasets from 9MiB to 100MiB) on several typologies of VMs (`XS: 1GiB RAM, 1 VCPU`, `S: 2GiB RAM, 2 VCPU`, `M: 4GiB RAM, 3 VCPU`, `L: 8GiB RAM, 4 VCPU`).
The result of these tests shows that the `4MiB` chunk size seems to be the best size compared to other chunk sizes (`2Mib`, `4MiB`, `8Mib`, `16Mib`, `32Mib`, `64Mib`, `128Mib`).
below is the average time per chunk size:

444: Fix the parsing of ndjson requests to index more than the first line r=Kerollmops a=Kerollmops
This PR correctly uses the `BufRead` trait to read every line of the content instead of just the first one. This bug was only affecting the http-ui test crate.

431: Fix and improve word prefix pair proximity r=ManyTheFish a=Kerollmops
This PR first fixes the algorithm we used to select and compute the word prefix pair proximity database. The previous version was skipping nearly all of the prefixes. The issue is that this fix made this method to take more time and we were trying to reduce the time spent in it.
With `@ManyTheFish` we found out that we could skip some of the work we were doing by:
- discarding the prefixes that were shorter than a specific threshold (default: 2).
- discarding the word prefix pairs with proximity bigger than a specific threshold (default: 4).
- remove the unused threshold that was specifying a minimum amount of word docids to merge.
We will take more time to do some more optimization, like stop clearing and recomputing from scratch the database, we will compute the subsets of keys to create, keep and merge. This change is a little bit more complex than what this PR does.
I keep this PR as a draft as I want to further test the real gain if it is enough or not if it is valid or not. I advise reviewers to review commit by commit to see the changes bit by bit, reviewing the whole PR can be hard.

441: Changes related to the rebranding r=curquiza a=meili-bot
_This PR is auto-generated._
- [X] Change the name `MeiliSearch` to `Meilisearch` in README.
- [x] ⚠️ Ensure the bot did not update part you don’t want it to update, especially in the code examples in the Getting started.
- [x] Please, ensure there is no other "MeiliSearch". For example, in the comments or in the tests name.
- [x] Put the new logo on the README if needed -> still using the milli logo so far

438: CLI improvements r=Kerollmops a=MarinPostma
I've made the following changes to the cli:
- `settings-update` become `settings`, with two subcommands: `update` and `show`.
- `document-addition` becomes `documents` with a subcommands: `add` (I'll add a feature to list documents later)
- `search` now has an interactive mode `-i`
- search return the number of documents and the time it took to perform the search.

430: Document batch support r=Kerollmops a=MarinPostma
This pr adds support for document batches in milli. It changes the API of the `IndexDocuments` builder by adding a `add_documents` method. The API of the updates is changed a little, with the `UpdateBuilder` being renamed to `IndexerConfig` and being passed to the update builders. This makes it easier to pass around structs that need to access the indexer config, rather that extracting the fields each time. This change impacts many function signatures and simplify them.
The change in not thorough, and may require another PR to propagate to the whole codebase. I restricted to the necessary for this PR.

433: fix(filter): Fix two bugs. r=Kerollmops a=irevoire
- Stop lowercasing the field when looking in the field id map
- When a field id does not exist it means there is currently zero
documents containing this field thus we return an empty RoaringBitmap
instead of throwing an internal error
Will fix https://github.com/meilisearch/MeiliSearch/issues/2082 once meilisearch is released

## Changes
The `matching_bytes` function takes a `&Token` now and:
- gets the number of bytes to highlight (unchanged).
- uses `Token.num_graphemes_from_bytes` to get the number of grapheme clusters to highlight.
In essence, the `matching_bytes` function now returns the number of matching grapheme clusters instead of bytes.
Added proper highlighting in the HTTP UI:
- requires dependency on `unicode-segmentation` to extract grapheme clusters from tokens
- `<mark>` tag is put around only the matched part
- before this change, the entire word was highlighted even if only a part of it matched
## Questions
Since `matching_bytes` does not return number of bytes but grapheme clusters, should it be renamed to something like `matching_chars` or `matching_graphemes`? Will this break the API?
Thank you very much `@ManyTheFish` for helping 😄
