fix failing CI, update python versions
drop 3.8 testing+support remove some 3.7 remnants add 3.13 and 3.14 testing+support silence pytest-asyncio deprecationwarning fix typing errors fix pep8 errors fix poetry warning
incorporates #271 and #272
this code base would also benefit from running flake8-upgrade (or similar) and replace all imports from typing that can be replaced with standard objects (e.g. List -> list) but I thought this PR was big enough already.
ugh, the runners don't have 24.04 + x64 + 3.14. They do have builds for 24.04 + 3.14 with other architectures, and 22.04 + x64 + 3.14.
Up to you if you want to keep it in ci.yml until it's available (presumably they'll have more builds once it exits the beta), remove it, do fancy matrix stuff for the ubuntu version, or whatever. @pgjones
Since mypy 1.16 --strict-bytes is enabled by default with --strict, which raised a couple new errors. I opened https://github.com/python-hyper/h2/issues/1305 and https://github.com/python-hyper/h11/issues/186 and widened a few types, but it's likely that a fair amount of the remaining 70-ish type hints, of which ~20 are parameters, using bytes can be widened.
