commit ab449343f9fe62ddc5de16bb535987308c26a916
Author: Sylvain Munaut <tnt(a)246tNt.com>

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.
