py-bitarray: update to 2.8.5.

2023-12-09   2.8.5:
-------------------
  * speedup unaligned copies by always using word shifts (in combination
    with builtin byte swap 64 when available) when bit-endianness and
    machine byte-order are opposite
  * add `HAVE_BUILTIN_BSWAP64` to header
  * avoid misaligned pointers when casting to `(uint64_t *)`
  * add tests
