Build a Python test infrastructure to test built VTTCompile output against known good state.

Research direction

Start by locating the VTTCompile command-line entry point and any existing test or build configuration. Use the open-sourced Selawik font with fonttools TTX to dump the relevant tables, rebuild them with VTTCompile, and dump the results again. Done means the test infrastructure compares the rebuilt tables against the known-good dumps.
