Per the ROM disassembly, the Vic's VIA outputs are inverted for the benefit of the serial bus.

Since the ROM is well disassembled, let's actually try to be a 1541 first.

Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful.

Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic.

Made an attempt also to trigger updates upon audio packets being returned, and significantly to reduce the size and quantity of those. This should get down to 11ms latency if the output wave is 44100; I might need to scale up the buffer size as the sampling rate increases or this is going to get crazy at 192Khz.

Increased buffering range of audio as a quick fix for now. Basically means: increased latency as a short-term fix.
