The Apple Sound Chip was primarily used by the Macintosh II to generate sound in hardware which was previously handled by the toolbox ROM with software interrupts.
Implement both the standard ASC and also the enhanced ASC (EASC) functionality which is used in the Quadra 800.
Note that whilst real ASC hardware uses AUDIO_FORMAT_S8, this implementation uses AUDIO_FORMAT_U8 instead because AUDIO_FORMAT_S8 is rarely used and not supported by some audio backends like PulseAudio and DirectSound when played directly with -audiodev out.mixing-engine=off.
