python3-bitstring: upgrade 4.1.4 -> 4.2.1

License-UPdate:
 format of LICENSE updated to "ASCII text, with CRLF line terminators"

Changelog:
==========
- Module crashes on import with 32-bit Python.
- Lists of integers not converted to bytes when using the bytes constructor.
- Empty comma separated tokens not handled correctly.
- Crash on import when docstrings not present due to optimize flag.
- Dropped support for Python 3.7. Minimum version is now 3.8.
- For tokens that use a non-numeric length, a ':' is now compulsory rather than
  recommended. For example use 'uint:foo' instead of 'uintfoo'.
- The previous e4m3float and e5m2float formats have become the slightly modified
  p4binary8 and p3binary8 formats.
- Some parameters are now enforced as positional only, such as auto in constructors.
