Use composite actions in CI (#65)

* Attempt composite actions in CI

* Remove needs monero-daemon for the action

* Correct actions folder layout

* Remove empty inputs/outputs, add shell

* Try moving env declaration spot

* Remove usage of env

* Cached Rust composite action

* Replace [] with ""

Remove empty outputs
