Make embedded-hal-async dependency optional for better compatibility with HALs
Some hals implement traits for embedded-hal version `=1.0.0.alpha.<not 9>`, which is
explicitly incompatible with the version `=1.0.0.alpha.9` which embedded-hal-async
depends on. Making the dependency optional allows downstream projects to include
rtic-monotonic without requiring that all of their other libraries also implement
that specific version of embedded-hal 1.0
