Starts to reformulate TMS collection as coroutines.
...
For the time being, thereby breaks all video. A static screen of the border colour is all you'll see.

The Master System mode, inevitably, is the test case.

Starts taking steps towards SMS/GG and V9938/9958 support.
...
Specifically: routine namespace stuff, plus the intention to move to a table-based operation+cost version of timing. Reordering works fine for the TMS, and probably would also for the SMS/GG, but it'd be problematic with the command engine of the V9938/9958 and maintaining a consistent set of code is easier.
