Starts to reformulate TMS collection as coroutines.

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

Thomas Harte
e7f4babf41
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.

a38639d099
Eliminates the concept of an iCoordinate.
...
Real-life precision appears not to support the idea of sub-sample pixel storage.

92065813ef
Ensures only the first 8px of sprites is output in 8x8 mode.

Also adds a little extra documentation.

This restores good sleeping behaviour.

Minor: ensure AY registers *read* as 0 from reset, as well as being 0.
