Merge #3948
3948: Fix hnsw internal panic by using another library r=ManyTheFish a=Kerollmops This pull request fixes #3923. The issue concerns the `hnsw` crate panicking due to a wrong call to the `[T]::copy_from_slice` function. I decided to switch the library to `instant-distance`, which is maintained [by someone of trust](https://lib.rs/~djc), who maintains a lot of very important crates. - [x] Make Clippy happy with the first commit. - [x] Reproduce the #3923 bug without this patch - [x] Check if the bug disappeared with this PR. - [x] Test with [the Algolia e-commerce dataset](https://www.notion.so/meilisearch/Algolia-Ecommerce-c5fa3b5f23a7485295df7e87306d5859).
