Let's build the Windows binary with lots of optimisation, as we're probably

going to package it as a precompiled binary.

Switch from make to meson as the build system (although wrapped in make for

simplicity). Much better. Refactor the fluxmap stuff from the global headers to
see how well it works --- it does.

Radically rework decoding: there's now a simple statistical clock guesser, and
...
then we read the pulsetrain into nice tidy bits with a proper clock, which
makes the decoder's job way easier. We can actually get rid of the entire MFM
decoder state machine. Also, after sorting out the magic bit patterns at the
beginning of records, we can now reliably pull them out of the bitstream
without needing to know anything about the records themselves.

Start work on an autocalibrator to detect precompensation, but something's gone

wrong and our reads are all bunk.

The USB capture/replay interface now uses timestamps rather than intervals;
...
this makes the hardware considerably simpler and more reliable (as I don't need
to spend time resetting the timers between pulses). Still doesn't help writes,
though. Simplify and improve clock detection; add an abortive attempt at an FM
decoder (turns out that the Brother doesn't use FM).

Rename decode to mfmdecode now that I've found what might be an FM disk.

Added the fluxdump command, for exporting a fluxmap into something like

Audacity where it can be visualised.

Add the test pattern generator back again. Try some experimental code to
...
convert a fluxmap into an encoding_buffer, but locking each pulse to a us grid.
I'm not sure whether this is good enough for reliable decoding, but early
indications look promising.

Refactor all the raw buffer stuff to be less bad. Add an encoded buffer, which

Realise that the weird data dropouts were due to a stray capacitor on the
...
board... so remove it. Better now. Also realise that PSoC Creator lies to you
about clocks, so adjust the sample clock to be derivable from the USB clock,
making it both the right frequency and much more accurate --- decode success is
dramatically improved (presumably due to less jitter). Redesign the capture
logic to use a timer; simpler now.
