SixtyFPS UI Library

Our infrastructure on GitHub was a big piece of work this week. We re-organized our GitHub actions. We now separate the "CI" step, run for every commit, with a snapshot step that creates artifact and packages.

We worked on binary C++ packages that do not require the programmers using SixtyFPS to have Rust installed.

This week we also started our work on adding support for micro controllers. This requires shrinking down the overall resource usage, which will benefit all platforms in the long run. The first commit towards MCU support was abb423.

Finally the CMake support on the C++ side saw a lot of polish this week, e.g. in commit 8a3b06.
