UAVCAN v1.0 done

[pavel-kirienko]

The library has been somewhat reworked. Don't look at the diff, it is too large -- this change is impossible to do incrementally in a sensible way.

The new implementation offers hard time complexity guarantees as discussed in OpenCyphal-Garage/libcyphal#185. The new implementation supports both Classic CAN and CAN FD without the need for compile-time configuration selection (#103). The new implementation offers a much simplified API that operates on contiguous memory buffers instead of small fixed-size blocks (https://forum.uavcan.org/t/canardrxtransfer-payload-reading/600).

After this PR is merged, I am going to do the branch swap: master will be v1.0, and the current master will become legacy-v0.

Fixes #131
Fixes #129 (this case is covered by tests)
Fixes #126
Fixes #125
Fixes #117 (completely new memory management)
Fixes #105
Fixes #104 (there is no DESIGN.md, the description has been moved into the header file)
Fixes #102 (100% test coverage)
Fixes #69 (https://forum.uavcan.org/t/platform-specific-components/768)
Closes #132

Disabled the codecov integration to prevent confusion. SonarQube is already set up to track the coverage correctly.

Some initial feedback.

[thirtytwobits]

So, I can approve this based on a cursory reading of the code but I'm not saying I did a "good" code review because it's big. If you want a real code review it'll take longer than this weekend to go though and compile this myself, use it, and dive into the implementation.

[pavel-kirienko]

That's understandable. I think we can afford some laxity until Libcanard v1.0 is released (the current version is 0.100); I suppose we will have a few months at least to get major API-breaking changes in, shall the need arise. For now, seeing as there don't seem to be any major issues, I would like to have it merged and the branches swapped.

[sonarcloud]

Kudos, SonarCloud Quality Gate passed!
