[TangerineSDR] TangerineSDR part and document numbering

Hi Scotty - well, I am concerned the document might become un-writable or
un-readable (maybe both).
It will have to cover: 3 kinds of receivers, a transmitter, a transceiver,
non-PSWS requirements.  Each section essentially becomes a matrix of
modules vs. requirements.

A common ICD is perhaps a bit easier, essentially 5 ICD's sequentially
combined into one document.
Each M.2 will be different but similar.  Similar in how things are
assigned,  but different because the
dual rx will use two-parallel busses of data, the transceiver will also,
but half will be going in the
opposite direction, the single receiver will be NoConnect on half, etc.
There will be multiple mechanical
outlines, (e.g. the transmitter will need a heatsink, the dual will be
bigger, etc.).

I'd like to propose we stick with just the RX Requirements document for now
just for time efficiency.
We can append or create new later after the Dual RX is well defined.
Similarly we can start the ICD with the
dual-receiver and append as we make progress.
