Support (read-only) WOZ1/WOZ2 images (#544) (PR #653)

Browse Source 
Supports:
- all "woz test images" v1.3 (WOZ1, WOZ2) are working, except 3.5"
- additionally: Frogger (spiradisc), Choplifter (not Enhanced //e!), Lode Runner, Marble Madness, Skyfox.
- woz images can be .gz or .zip compressed (ie. same as other supported images)
- save-state

Limitations:
- read-only, so WOZ images are forced to be write-protected
  . as a result, games that need r/w images won't work (Stickybear Town Builder, Wizardry)
- 5.25" only (not 3.5")
