- Rename crate as `hs-bindgen-attribute` since it define an attribute macro and
  not a derive one ...

- Rely on `hs-bindgen-types` rather than `hs-bindgen-traits` (for `antlion`
  sandbox too) ;

- Read new `hsbindgen.toml` config filename side to legacy `.hsbindgen` one ;

- Ensure that function signature does not contain too much args … (to prevent
  GHC C-ABI implementation bugs on platform apart from x86_64) ;

- Add GitHub Action tests for `--features full`!
