Added
- Support for compilation on PowerPC big-endian platforms.
- Type annotations and stub files for Cython modules.
Changed
- [`distutils`](https://docs.python.org/3/library/distutils.html) is now used to compile the package, instead of calling `autotools` and letting HMMER configure itself.
- `Bitfield.count` now allows passing an argument (for compatibility with [`collections.abc.Sequence`](https://docs.python.org/3/library/collections.abc.html#collections.abc.Sequence)).
