WDSP receiver plugin

WDSP receiver plugin

This plugin implements a Rx channel based on the WDSP library. It implements issue #2156. This is a powerful and feature rich DSP library for SDR more specifically amateur radio and SWL audio modes: SSB, CW, AM, FM. The WDSP library is at the heart of OpenHPSDR and Pi-HPSDR projects and both implement excellent communication receivers. Experience with Pi-HPSDR was the main motivation to create this plugin.
