OTIO 0.17.0 Release Prep

[markreidvfx]

Preparing the AAF adapter repo for release of OpenTimelineIO 0.17.0 that ships without adapters.

I tried my best to keep this somewhat matching the style of the ALE adapter. This repo is different in that it uses a wheel for all the tests. This is so we are testing the same thing that will users will install.

I also took the opportunity to convert the setup.py to pyproject.toml

I tried to update the codecov-action to v4 but they require some sort of token now that I'm not sure how to generate yet.

Looks good. Really no show-stopping comments, but left some in there for your consideration.

Also I think you'll need to update the python badge in "README.md" to add 3.11.
In the other adapters we fetch the tested python versions dynamically from the ci file.

lgtm, approving pending updates per @apetrynet

@apetrynet it should be all good now, sorry for the delay. I removed the .dev1 like you suggested. I also added the dynamic badges, I didn't know that was a thing now :). I'll remove using @extract_adapters branch once it has been merged into the main OpenTimelineIO repo. I also rebased it on top of the current main.
