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

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.

fluxmap: Don't push_back() if Fluxmap begins with F_DESYNC.
...
Fluxmap::split() creates a 0-length Fluxmap if the Fluxmap
begins with F_DESYNC. Fix this by not doing push_back()
if a F_DESYNC is encountered at the start of the Fluxmap.

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.

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
(because streams in C++ are terrible).

Behemoth change to rework everything to use Bytes rather than vectors of

uint8_t. The tests pass, but of course, nothing decodes any more.
