Changes:
- Fixed LimeSDR channel selection
- Fixed RTL-TCP not saving settings
- Fixed FFT size change causing a crash
- Added PPM setting to RTL-TCP and RTL-SDR sources
Important: See readme for dependencies, the MacOS and Ubuntu/Debian packages don't include them.
Note: The MacOS package doesn't create an icon, run sdrpp in a terminal to run SDR++. Also, it's is missing quite a few source modules, please wait a few more days for me to fix that.
