chore: don't panic on unknown bus and io writes/reads
...
This will lead to emulation bugs due to devices I've yet to implement but by
doing this a lot of games become playable "by default" such as Doom or
Kirby: Nightmare in Dream Land.
When implementing feature and/or debuggin make sure to set:
panic_on_und_bus and panic_on_und_io to true so that the emu crashes
on unknown reads/writes
