Add an extremely crude method to slow things down
...
It's not configurable, and not accurate to any particular measure. But
it's something for now.

Avoid polling for events until we're ready for a frame redraw
...
This change drastically cuts the number of times we poll for events, and
consequently drastically speeds up the number of frames we can draw
within any given span of time.
In other words, we go from "this barely moves as fast as the actual
Apple II" to "holy shit this moves so fast".

That doesn't seem to be how the motor on/off status works. This
basically stops the motor from actively spinning, but it does not
prevent the drive from basic operation.

Rewrite SBC logic
...
The carry handling was incorrect; carry is set if we went below zero,
but bit 7 is not enough to determine that. It follows that negative
handling needed to be modified accordingly. Overflow handling was also
incorrect.

Several changes...
...
1. We have much more logging.
2. We were not properly turning off drives when we would get called with
C0x8.
3. We now roll over sector pos if we are greater than ENC_ETRACK.
4. We now reset sector pos when we step.

Just checking if (cpu->eff_addr) is not sufficient. We need to check the
address mode; only increment or decrement the A register if the mode is
literally ACC.
