Types crate v2

[TTWNO]

• Separate -types into their own crate. This crate should be compileable on basically any system.
• Separate -client into its own crate. This crate is the equivalent of the old "client-accessories" features.
• Fix all clippy warnings, add --workspace flag.
• Fix semver checks (it only work on a crate-by-crate basis)
• Approval from other involved individuals.

Please rebase and update enumflags2.

[TTWNO]

Enumflags2 was downgraded in #87 are you wanting me to reverse that change?

[TTWNO]

Also, I have merged main into this branch instead of rebasing, since that was the recommended step from the Github interface. I can also rebase if you'd like that better.

[TTWNO]

Ah ha! Finally found the culprit!

I probably need to move a few more things to be workspace deps, but now the tests finally work! Only took a dozen tries 😆

[TTWNO]

Fixed enumflags2; I didn't realize that the version had been upgraded not downgraded. My bad.

P.S.: This code coverage report is super clear now that we can see the different subcrates: https://app.codecov.io/gh/odilia-app/atspi/pull/82/tree

I know this breaks the CI, but could we merge this? The error is a sign of another bug that needs to be addressed.

I'll help merge the other PRs once this is merged.

[TTWNO]

I'm going to merge this. This PR is blocking too many other PRs, development of Odilia, and general progress. I'm happy to continue submitting smaller PRs after this, but I'm happy with this in its current state, and it has all the changes applied to main since the branch.
