Standalone phone operation with Quisk

This Standalone configuration is mainly for Digimodes operation. The provided Quisk setup though has a dual configuration installed, one for digimodes named "PiSDR Digi" as the default one and one for phone operation named "PiSDR", user can select ad-hoc each one that wishes to operate exclusively. Needs to be mentioned though that when user wants to operate phones, a third-party provided USB mic is required that should be connected to one of Pi SDR IQ Plus USB ports, since the on-board mic jack cannot be used in this configuration.
