I added (imperfect) memory conflict timing to the SA1.

Before:

  - WRAM↔↔ROM ran 7% too fast
  - ROM↔↔ROM ran 100% too fast
  - WRAM↔↔IRAM ran 7% too fast
  - ROM↔↔IRAM ran 7% too fast
  - IRAM↔↔IRAM ran 287% too fast
  - BWRAM↔↔BWRAM ran 100% too fast
  - HDMA ROM↔↔ROM ran 15% too fast
  - HDMA WRAM↔↔ROM ran 15% too fast
  - DMA ROM↔↔ROM ran 100% too fast

After:

  - ROM↔↔ROM runs 14% too fast
  - HDMA WRAM↔↔ROM runs 7% too fast
  - DMA ROM↔↔ROM runs 4% too fast

If you enable this with the fast PPU + DSP, your framerate in SA1 games
will drop by 51%. And even if you disable it, you'll still lose 9% speed
in SA1 games, and 2% speed in non-SA1 games, because of changes needed
to make this support possible.

By default, I'm leaving this off. Compile with `-DACCURATE_SA1` (or
uncomment the line in sfc/sfc.hpp) if you want to try it out.

This'll almost certainly cause some SA1 regressions, so I guess we'll
tackle those as they arise.
