IMPORTANT: the transmitter prefers 3.3V, it stops working after a
while on 5V.

======
Sampled at 192k samples/second, found that the transmissions had 3
types of (presumably square) pulses:
======== ======= ========
name samples duration
======== ======= ========
narrow 200 ~ 1ms
middle 300 ~ 1.5ms
wide 400 ~ 2ms
======== ======= ========
The two sequences are:
* ``nnnnnnWnWnnMnnMnnnnnWnnnnMnMWn``
* ``nnnnnnWnWnnMnnMnnnnnnnnnnWMMWn``
Actually no, the pulses are not ½ high and ½ low, they're shaped
weird. The source code has the correct widths.
