NOTE: The token_at_depth is method is a bit useless now, as the only
cases where there would be a toke at depth 1000 are the cases where
the parser already stack-overflowed earlier.
Example: (((((... (x=1) ...)))))
602: Use mimalloc as the default allocator r=Kerollmops a=loiclec
## What does this PR do?
Use mimalloc as the global allocator for milli's benchmarks on macOS.
## Why?
On Linux, we use jemalloc, which is a very fast allocator. But on macOS, we currently use the system allocator, which is very slow. In practice, this difference in allocator speed means that it is difficult to gain insight into milli's performance by running benchmarks locally on the Mac.
By using mimalloc, which is another excellent allocator, we reduce the speed difference between the two platforms.

606: Make binaries faster on release profile through better compile options r=Kerollmops a=loiclec
Using `codegen-units = 1` and `lto = 'thin'` makes the compile time a bit longer, but also produces faster binaries.
I'd like to run milli's benchmark with these options, so that we can see whether it is worth enabling on meilisearch.

2523: Improve the tasks error reporting when processed in batches r=irevoire a=Kerollmops
This fixes#2478 by changing the behavior of the task handler when there is an error in a batch of document addition or update.
What changes is that when there is a user error in a task in a batch we now report this task as failed with the right error message but we continue to process the other tasks. A user error can be when a geo field is invalid, a document id is invalid, or missing.
fixes#2582, #2478

601: Introduce snapshot tests r=Kerollmops a=loiclec
# Pull Request
## What does this PR do?
Introduce snapshot tests into milli, by using the `insta` crate. This implements the idea described by #597
See: [insta.rs](https://insta.rs)
## Design
There is now a new file, `snapshot_tests.rs`, which is compiled only under `#[cfg(test)]`. It exposes the `db_snap!` macro, which is used to snapshot the content of a database.
When running `cargo test`, `insta` will check that the value of the current snapshot is the same as the previous one (on the file system). If they are the same, the test passes. If they are different, the test fails and you are asked to review the new snapshot to approve or reject it.
We don't want to save very large snapshots to the file system, because it will pollute the git repository and increase its size too much. Instead, we only save their `md5` hashes under the name `<snapshot_name>.hash.snap`. There is a new environment variable called `MILLI_TEST_FULL_SNAPS` which can be set to `true` in order to *also* save the full content of the snapshot under the name `<snapshot_name>.full.snap`. However, snapshots with the extension `.full.snap` are never saved to the git repository.
## Example
```rust
// In e.g. facets.rs
#[test]
fn my_test() {
// create an index
let index = TempIndex::new():
index.add_documents(...);
index.update_settings(|settings| ...);
// then snapshot the content of one of its databases
// the snapshot will be saved at the current folder under facets.rs/my_test/facet_id_string_docids.snap
db_snap!(index, facet_id_string_docids);
index.add_documents(...);
// we can also name the snapshot to ensure there is no conflict
// this snapshot will be saved at facets.rs/my_test/updated/facet_id_string_docids.snap
db_snap!(index, facet_id_string, docids, "updated");
// and we can also use "inline" snapshots, which insert their content in the given string literal
db_snap!(index, field_distributions, `@"");`
// once the snapshot is approved, it will automatically get transformed to, e.g.:
// db_snap!(index, field_distributions, `@"`
// my_facet 21
// other_field 3
// ");
// now let's add **many** documents
index.add_documents(...);
// because the snapshot is too big, its hash is saved instead
// if the MILLI_TEST_FULL_SNAPS env variable is set to true, then the full snapshot will also be saved
// at facets.rs/my_test/large/facet_id_string_docids.full.snap
db_snap!(index, facet_id_string_docids, "large", `@"5348bbc46b5384455b6a900666d2a502");`
}
```
