Update xxhash to 3.8.1

[pyup-bot]

This PR updates xxhash from 2.0.2 to 3.8.1.

Changelog

3.8.0

~~~~~~~~~~~~~~~~~

- Speed up module-level one-shot ``digest()``, ``intdigest()``, and
``hexdigest()`` functions by switching them to ``METH_FASTCALL``.
- Keep one-shot argument handling consistent with hash constructors, including
positional and keyword ``input``/``seed`` arguments, duplicate argument
errors, and oversized seed wrapping.
- Fix error handling in the ``xxh3_128`` integer digest path so allocation
failures are reported cleanly.
- Fix Python 3.8 builds by adding a ``PyModule_AddType`` compatibility
fallback with correct reference counting.
- Correct type stubs for ``xxh64_digest()``, ``xxh64_hexdigest()``, and
``xxh64_intdigest()``, they were incorrectly aliased to xxh3_64 functions.

3.7.1

~~~~~~~~~~~~~~~~~

- Fix memory leak in copy() and new() when memory allocation fails (rare edge case)
- Fix seed/reset state initialization in xxh32 and xxh64 (unlikely to affect normal usage)
