Gamegear audio is now stereo (finally!). Thanks to Justin Kerk for prodding me to get it done, as well as providing recordings from his gamegear which I used to tweak the PRNG with (it still may be offset in time by one bit...) Please let me know if anyone runs into any issues with this or any of the other chips covered by sn76496.c
