Updates cachetools from 5.5.2 to 6.0.0

Changelog

Sourced from cachetools's changelog.

v6.0.0 (2025-05-23)

• Require Python 3.9 or later (breaking change).

• Remove MRUCache and the @func.mru_cache decorator (breaking change).

• Add an optional condition parameter to the @cached and @cachedmethod decorators, which, when used with a threading.Condition instance, should improve cache stampede <https://en.wikipedia.org/wiki/Cache_stampede>_ issues in massively parallel environments. Note that this will inflict some performance penalty, and therefore has to be enabled explicitly.

• Convert the cachetools.func decorators to use a threading.Condition instance to deal with cache stampede <https://en.wikipedia.org/wiki/Cache_stampede>_ issues. Note that this may result in a noticable performance degradation, depending on your actual use case.

• Deprecate support for cache(self) returning None to suppress caching with the @cachedmethod decorator.

• Improve documentation.

• Update CI environment.
