Pad Not TCP with zeros
171c10d 
In testing on real hardware (Fomu), I was missing a lot of "tail end"
packets... like, a *lot* of them. This prevented clients from getting
the full body, hanging up, etc etc.

This seems to be related to the 64B packet size of the USB ACM CDC TLA
WTF protocol we're using under the hood. I haven't checked the gateware,
but it's *acting like* it doesn't send the packet until there's >64B in
the buffer. (Or maybe 64 exactly, and I was doing my math wrong before.)

Luckily, we haven't been using "Stream ID zero", so we can redefine Not
TCP such that
8000
 every packet begins with a nonzero byte (stream ID), and
zero bytes between packets are ignored. Then, pad on the device side,
and *wham*, working.

(Mostly. The LED endpoint doesn't always want to finish its job; needs
more investigation.)
