Add emulators/anese: NES Emulator written for fun and learning

ANESE (Another NES Emulator) is a Nintendo Entertainment System Emulator written
for fun and learning.

Accuracy and performance are long-term goals, but the primary focus is getting
popular titles up and running. There are still a lot of bugs, but many games are
working quite well already.
