291: Fix a bug about zero bytes in the inputs r=irevoire a=Kerollmops

Ok, good news, after a little session of debugging with `@irevoire` we found out that the bug seems to be related to zeroes in the input update. The engine wasn't designed to accept those. The chosen solution is to update the tokenizer to remove those zeroes. We are waiting on https://github.com/meilisearch/tokenizer/pull/52 to be merged and a new version to be released.

It is not an undefined behavior, I repeat: it is a "normal" bug 🎉 👏

----

This PR tries to fix a bug where we use LMDB in the wrong way, leading to panic due to an undefined behavior on the Rust side. I thought [we fixed it in a previous PR](https://github.com/meilisearch/milli/pull/264) but we found out that _a similar_ bug was still present. `@bb` found a way to trigger this bug and helped us find the origin of it.

As I don't have a minimal reproducible example of this bug I bet on the unsafe `put_current` calls when we index new documents as the bug was trigger after a big indexation on a clean database, thus not triggering a deletion update. I only replaced the unsafe `put_current` with two safe calls to `get`/`put`.

I hope it helps and fixes the bug, only `@bb` can help us check that. I am not even sure how I can create a custom Docker image and expose it for testing purposes.

254: Improve the facet string distribution speed r=Kerollmops a=Kerollmops

This pull request creates a data structure similar to the one we use for the faceted numbers, a tetratomic decision tree but this time for the facet strings. This PR also changes the facet distribution behavior by returning one of the original facet values, fixes #260.

This data structure defines bucket-like structures where documents ids are stored under their facet value and helps the search decide if it wants to move to a lower level under a given bucket or not, depending on if the current bucket contains interesting documents or not. The whole format, algorithm, and previous attempts are explained in the [`facet_string.rs` file](ec1cfdd42b/milli/src/search/facet/facet_string.rs).

Note that this data structure **could** be used to sort by string lexicographically, that hypothetically possible. We need more testing, in terms of performance and quality, as we will sort on lowercased versions of the facet values.

 - [x] Implement a faster and more precise way to fetch the facet distribution.
 - [x] Store and return the original facet string value. We currently return the lowercased version.

283: Use the AlwaysFreePages flag when opening an index r=irevoire a=Kerollmops

We introduced a new flag in our fork of LMDB, this `AlwaysFreePages` flag forces LMDB to always free the single pages it uses before writing to the disk instead of keeping them in a linked list.

Declaring this flag reduces the memory print (leak) we have on memory after indexing a lot of documents.

Fixes #279.

269: Fix bug when inserting previously deleted documents r=Kerollmops a=Kerollmops

This PR fixes #268.

The issue was in the `ExternalDocumentsIds` implementation in the specific case that an external document id was in the soft map marked as deleted.

The bug was due to a wrong assumption on my side about how the FST unions were returning the `IndexedValue`s, I thought the values returned in an array were in the same order as the FSTs given to the `OpBuilder` but in fact, [the `IndexedValue`'s `index` field was here to indicate from which FST the values were coming from](https://docs.rs/fst/0.4.7/fst/map/struct.IndexedValue.html).
