Merge #288

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.
