ENH, MAINT: workunit quirks to fix

[tylerjereddy]

When working on more complex workunits, changing from one fundamental type to another is not supported, which is surprising:

    ^^^^^^^^^^^^^^^

The error message when declaring but not initializing also leaves the developer a bit confused perhaps:

Finally, some errors go stdout instead of stderr, which is pretty confusing:

Test case was Conclusion(status=Status.INTERESTING, interesting_origin=(<class 'SystemExit'>, '/home/tyler/github_projects/pykokkos/pykokkos/core/translators/static.py', 140, (), ())) on first run but Conclusion(status=Status.INTERESTING, interesting_origin=(<class 'ImportError'>, '<frozen importlib._bootstrap>', 241, (), ())) on second

It looks like this comes down to pretty_print() literally using print() in pykokkos/core/visitors/visitors_util.py .
