misc: Add an utility to modulate a RACH burst

The output is only 1sps and needs to be filtered by an RRC filter (0.35) before transmission.

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.
