Sylvain Munaut aa207a8cc7 sdr/pi4cxpsk: Add support for pi/2-CBPSK 
The rotation is not always pi/4 now.
Ideally everything should get renamed but that's a big diff and
will be done later.

Sylvain Munaut a23f3d3243 sdr/pi4cxpsk: Add a method for modulation of pi/4 CxPSK bursts 
This currently only supports 1sps. To upconvert, it should be
convoluted with a RRC filter.

It required adding a second table of symbol in the modulation
type where the entries are sorted by the 'bits' value rather
than the symbol number.

Sylvain Munaut b067a532de l1/punct: Extend the puncture table generation to support TCH6/9 
The scheme used in TCH6/9 is a bit special, with different puncture
mask for the beginning / center / end. It also doesn't repeat the
mask all the way through.

This adds support for this kind of stuff.
