Dear maintainer(s),

In Python 3.6, asyncore and asynchat have been formally marked as
deprecated. Code that imports these libraries will no longer work from
Python 3.12, which is currently in Trixie.

Since pysendfile uses either of these Python libraries, please prepare
for this removal and migrate away from them.

See this link for more details:
https://peps.python.org/pep-0594/#deprecated-modules

Cheers,
