Add a .power_assertable?/2 check and allow fallback to assert

[sitch]

In order for a more seamless experience, having an introspection to see if there is a breaking macro or some other thing that would either fail to expand or be outside of a reasonable .power_assert/2 call, just fail this check and revert to the default "assert" call

Thank you for your feedback!
It looks convenient, but is there a more detailed use case or a specific problem?

Just allows for a more seamless fallback strategy so can just flat out replace assert
