Cbor2

- Fixed ``CBORSimpleValue`` allowing the use of reserved values (24 to 31) which resulted in
invalid byte sequences
- Fixed encoding of simple values from 20 to 23 producing the wrong byte sequences

- The ``cbor2.encoder``, ``cbor2.decoder`` or ``cbor2.types`` modules were deprecated – import
their contents directly from ``cbor2`` from now on. The old modules will be removed in the next
major release.
- Added support for Python 3.12
- Added type annotations
- Dropped support for Python 3.7
- Fixed bug in the ``fp`` attribute of the built-in version of ``CBORDecoder`` and
``CBOREncoder`` where the getter returns an invalid pointer if the ``read`` method of
the file was a built-in method

- Fix MemoryError when decoding Tags on 32bit architecture. (Sekenre)

- Added official Python 3.11 support (agronholm)
- Raise proper exception on invalid bignums (Øyvind Rønningstad)

- Documentation tweaks (Adam Johnson)
