chore: github workflow to run tests (#12)

Adding github workflow to run rust tests as well as integration tests.
As part of that cleaned up use of _nightly_ feature and removed dependency on `cargo-expand` 
module in order to keep the workflow fast.

- chore: build+test workflow
- chore: remove str_split feature annotation
- chore: setup dart and pub for ci tests
- chore: adding llvm to github actions
- rid-build: expanding without cargo expand
- chore: rustc expand needs nightly rust
- chore: final cleanup of github action
