Support StrongEnum

[ducky64]

Will be looking into this 'soon', along with other simple quality-of-life fixes like #105.

That being said if you have code that is PR-ready (architecturally clean and code quality clean) reviews probably happen faster...

I worked on this a while ago and ended up blocked on available Enum APIs (see #111)

@hngenc I think what I need is a programmatic way to get a literal given the enum hardware object (EnumType) and the number the enum corresponds to. Though EnumFatory has apply(UInt), EnumType.factory is private (as it should be) - so maybe we can expose a specific API in DataMirror, like DataMirror.intToEnum(int, chiselTypeOf(enumHardwareObject)). Or, more broadly, DataMirror.enumFactoryOf(enumHardwareObject)?

hi, I'm trying this framework in my project, and the project is heavily based on StrongEnum within Bundle. It would be quite helpful if peek/poke of StrongEnum is supported.

I wonder if you plan to add support for StrongEnum in recent snapshots?

Currently, I have a workaround in my local branch to allow me to test StrongEnum in Bundles that mimics the implementation of the chisel-iotesters with Pokeable.
It seems feasible by adding the Element version of peek/poke/expect etc in the backend.

Let;s track this in #291
