Partial conversion to do automatic scaling of flux based on the disk rotation
...
speed. Although, something seems to have broken for 5.25" disks.

Massive refactor to work in logical cylinders everywhere. The logical/physical
...
mapping is now done at the last stage and should, ideally, be automatic. I'm
sure there are bugs everywhere.

Refactor for better multi-read support. Each read is now held separately, with
...
F_DESYNC being deprecated, and FluxSource returns an iterator which can be used
to retry reads.

Don't spin in an infinite loop if the decoder tries to find a data record and
...
the matcher fails to find anything, leaving the seek point unchanged.

Add option to rescale flux sink pulses.
...
Note that this does not affect the decoder used for verify,
but at least for tame rescaling the decoders are still able to
lock.
This is a precursor to automatic scaling via the disk speed
measurement.

Rework the flux decoders to add a desync opcode for separating multiple reads
...
in a flux stream. Finally add a unit test for the flux decoder.

Rework the bytecode format to use a much simplified setup: a six-bit timer with
...
the top two bits reserved for pulse and index state. This is actually smaller,
bandwidth-wise, than the old version, and may be smaller than the crunched
version.

match them). The IBM decoder is now properly converted, autodetecting FM and
MFM.

The new decoder architecture now works, at least for the FB100. All I need now

is to rewrite every single other decoder.

Beat the Kryoflux stream reader into enough shape that it will handle the weird

Kryoflux index markers; refactor it to use Bytes rather than raw streams

Splitting by hard sectors works, up to a point; we can correctly decode (with

CRC checking!) most of the Zilog MCS disk. However, we're still stumped by the
