add trivial module for backwards compatability

[akaszynski]

This PR adds a trivial file to make our recent theme changes compatible with pyvistaqt. I don't want our theme changes to be a breaking change as this needs to be out soon in support of another project https://github.com/pyansys/pymapdl.

Merging as this is a trivial change.

Out of curiosity, where/how is this new module used in pyvistaqt? I tried looking for theme in that repo but couldn't find it.

Ah, I see, this was fixed in pyvista/pyvistaqt#108 which is why the search didn't turn up anything. Thanks.
