Publish new version

[aDotInTheVoid]

Currently https://lib.rs/crates/fxhash and https://crates.io/crates/fxhash both show let mut hashmap = FxHashMap::new();, which is wrong (#1)

The README here has been fixed, but it would be great if a new version could remove this mistake from other sources

Starting to wonder if this crate is being maintained any more...

I think it is worth to mention https://github.com/rust-lang/rustc-hash
