Test relevant safety guarantees via miri, adress sanatiser and leak sanatiser

[CommanderStorm]

We currently don't test for savety, just for basic correctness.

This is especially important, given that we run some Cpp below us and if there is mismatch, this could spawn dragons, make pigs fly out of our noses or something worse.

Here is a basic CI draft implementing this

I have done a bit of poking into miri and it seems to be more involved than I currently want to poke.
I have left the relevant code commented out

• chore(ci): Make sure to test all platforms in CI #32

Edit:

      # Test MIRI
