Support for Python 3.13

[SamEdwardes]

I imagine this may be on your radar, but just in case it is not, I am having some issues installing with Python 3.13. Thanks for the work on all your awesome tools!

        ********************************************************************************
        ############################
        # Package would be ignored #
        ############################
        Python recognizes 'srsly.ujson.lib' as an importable package[^1],
        but it is absent from setuptools' `packages` configuration.

        This leads to an ambiguous overall configuration. If you want to distribute this
        package, please make sure that 'srsly.ujson.lib' is explicitly added
        to the `packages` configuration field.

        Alternatively, you can also rely on setuptools' discovery methods
        (for example by using `find_namespace_packages(...)`/`find_namespace:`
        instead of `find_packages(...)`/`find:`).

        You can read more about "package discovery" on setuptools documentation page:

        - https://setuptools.pypa.io/en/latest/userguide/package_discovery.html

        If you don't want 'srsly.ujson.lib' to be distributed and are
        already explicitly excluding 'srsly.ujson.lib' via
        `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
        you can try to use `exclude_package_data`, or `include-package-data=False` in
        combination with a more fine grained `package-data` configuration.

        You can read more about "package data files" on setuptools documentation page:

        - https://setuptools.pypa.io/en/latest/userguide/datafiles.html


        [^1]: For Python, any directory (with suitable naming) can be imported,
              even if it does not contain any `.py` files.
              On the other hand, currently there is no concept of package data
              directory, all directories are treated like packages.

Besides the required code changes to use the buffer protocol, this will probably require upgrading cython, which is blocked by the issue mentioned in #97

[SamEdwardes]

Thank you! I figured this was on your radar. Just wanted to share in case.

[salty-horse]

I'm not related to the project. Just came here because I had the same issue :)

Porting over at least msgpack/msgpack-python#383 and msgpack/msgpack-python#468 would probably be a start, but I wouldn't be surprised if there were more.

Is srsly.msgpack regarded as a permanent fork of msgpack, or is it intended to be possible to sync it up with current versions? It seems to be several years behind.
