Redesign of I/Q recording
Creation of a new FileSink (or File Recorder) channel plugin. Consequently the recording feature of all relevant device plugins has been removed. This changes the way recording I/Q is made. Now you have to add this FileSink plugin in the Channels area using the channel selector. This is more consistent since this concerns the recording of the baseband and offers new functionality:
- Possibility to record only part of the baseband (decimation by a power of two) centered anywhere (use of a NCO)
- Possibility to record multiple parts of the same baseband simultaneously
- So called "spectrum squelch" to trigger recording when some part of the power spectrum exceeds a threshold value
Also consequently the former FileSink output device plugin has been renamed to FileOutput making it consistent with the devices and channels naming convention.
