Merge #438

438: Bump MSRV to 1.59, switch to Edition 2021. Fix CI. r=therealprof a=Dirbaio

Bump MSRV to 1.59, switch to Edition 2021.

Fixes CI, It broke due to yanking `cortex-m-rt 0.71` due to the stack align bug.

~~I don't think the MSRV should matter for `dev-dependencies`? They're only required for running tests, bumping it doesn't affect crates using `embedded-hal` as a regular dep.~~ of course *out* CI requires it, duh.
