protocol.vgm: use Fraction instead of float.

Avoids loss of precision.

applet.audio.yamaha_opl: unmark as preview.

Seems to work reliably after the migration to pushback (9da056d5).

applet.audio.yamaha_opl: use write pushback instead of hax.

applet.audio.yamaha_opl: simplify audio bitstream receiver.

access.direct.demultiplexer: revert non-equivalent transformation.

access.direct.demultiplexer: improve robustness of OUT pushback.

OUT pushback used to result in crashes with small write buffers, and
in general it did not take into account in-flight requests.

access.direct.demultiplexer: add read(flush=False).

In some cases (e.g. Yamaha OPx applet), the IN and OUT channels are
completely independent, and interlocking between them is undesirable
as it will lead to unnecessarily increased latency.

access.direct.demultiplexer: simplify _out_slice().

This function didn't actually do what the comment said it did, and it
was very complicated, so now the slow path simply aggregates up to
one packet of data instead of trying to do weird aligned things.

access.direct.demultiplexer: fix pushback log message. NFC.
