egprs: Enable 8-PSK burst detection when EDGE is enabled
The command line EDGE option will enable 8-PSK burst
detection on any slot where a normal burst is expected.
The burst search order is 8-PSK first followed by GMSK.
EDGE will force 4 SPS sampling on Tx and Rx. Along with
twice the search correlation from 8-PSK and GMSK, EDGE
will increase CPU utilization. Whether the increase is
notable or not is dependent on the particular machine.
