Cbor2

- Fixed decoding of epoch-based dates being affected by the local time zone in the C extension

- Fixed `__hash__()` of the C version of the `CBORTag` type crashing when there's a recursive reference cycle
- Fixed type annotation for the file object in `cbor2.dump()`, `cbor2.load()`, `CBOREncoder` and `CBORDecoder` to be `IO[bytes]` instead of `BytesIO`
- Worked around a [CPython bug](https://github.com/python/cpython/issues/99612) that caused a `SystemError` to be raised, or even a buffer overflow to occur when decoding a long text string that contained only ASCII characters
- Changed the return type annotations of `cbor2.load()` and `cbor2.load()` to return `Any` instead of `object` so as not to force users to make type casts

- Fixed use-after-free in the decoder's C version when prematurely encountering the end of stream
- Fixed the C version of the decoder improperly raising `CBORDecodeEOF` when decoding a text string longer than 65536 bytes

- Added the `cbor2` command line tool (for `pipx run cbor2`)
- Added support for native date encoding (bschoenmaeckers)
- Made the C extension mandatory when the environment variable `CBOR2_BUILD_C_EXTENSION` is set to `1`.
- Fixed `SystemError` in the C extension when decoding a `Fractional` with a bad number of arguments or a non-tuple value
- Fixed `SystemError` in the C extension when the decoder object hook raises an exception
- Fixed a segmentation fault when decoding invalid unicode data
- Fixed infinite recursion when trying to hash a CBOR tag whose value points to the tag itself
- Fixed `MemoryError` when maliciously constructed bytestrings or string (declared to be absurdly large) are being decoded
- Fixed `UnicodeDecodeError` from failed parsing of a UTF-8 text string not being wrapped as `CBORDecodeValueError`
- Fixed `TypeError` or `ZeroDivisionError` from a failed decoding of `Fraction` not being wrapped as `CBORDecodeValueError`
- Fixed `TypeError` or `ValueError` from a failed decoding of `UUID` not being wrapped as `CBORDecodeValueError`
- Fixed `TypeError` from a failed decoding of `MIMEMessage` not being wrapped as `CBORDecodeValueError`
- Fixed `OverflowError`, `OSError` or `ValueError` from a failed decoding of epoch-based `datetime` not being wrapped as `CBORDecodeValueError`

- 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
