Refactors a MixerReader instance from the RealMixerSource so that it can be reused for both real and complex data outputs. Updates RealMixerSource to use refactored MixerReader and use a default sample rate of 8 kHz. Updates the ComplexMixer to use the refactored MixerReader. Updates the FCD 1/2 tuners for compatibility with the new ComplexMixer. Removes several unused classes.
