451523bdef Support for custom output bitrate, e.g. to target //gs in 2.8MHz mode.
For some reason playback speed is only about 1.6x (probably due to
slowing down accesses to the I/O page to 1MHz, so as not to mess up
hardware timings), but happily this comes within 3% of being 44100/2.

bd0aa6ad6b Simplify the accounting of audio ticks in video framing, and fix an off-by-one that was causing audio and video to become desynchronized.
Switch from 14340Hz to 14700Hz, which is 44100/3 i.e. a divisor of the
most common audio input sample rate.  This gives better quality
(and/or faster to encode) audio quality at the cost of producing <2%
faster playback.
