1528: Update of the Date Time Format in commitDate r=MarinPostma a=irevoire
Since we were relying on a [super old version of `vergen`](https://docs.rs/crate/vergen/3.0.1), we could not get the `commit timestamp`, so I updated `vergen` to the latest version.
This also allows us to remove all the features we don't use.

288: Stop tracking the Cargo.lock and add cache + windows to the CI r=curquiza a=irevoire
We reuse the same `~/.cargo` and `./target` directory between each run on the same OS and rust toolchain.
The `key` to decide if we can use the cache or not is: `$OS_NAME-$RUST_TOOLCHAIN-$HASH(Cargo.toml)`
We also removed the `Cargo.lock` from this repository. Indeed, milli is a library and [should not track the `Cargo.lock`](https://doc.rust-lang.org/cargo/guide/cargo-toml-vs-cargo-lock.html)
And finally, we enabled the tests on `windows-latest`. Since `lmdb` has been updated, this is now possible.

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.
