[AT3P] Add advanced option for GHA debug

There are 3 flags:
GHA_PASS_INPUT - allows to pass source signal in to the filter
GHA_WRITE_TONAL - allows to write result of GHA into the bitstream
GHA_WRITE_RESIUDAL - allows to process signal after the filter

If all 3 flags set it denotes normal processing.
If we want to see only result of sinusoid extraction (tonal component) we can set only
GHA_WRITE_TONAL flag. If we want to see signal after  extraction we need
to set GHA_PASS_INPUT and GHA_WRITE_RESIUDAL.
