[AT3P] Update libgha. Experiment with upsample frame during GHA.
This should improve accuracy of sinusoid extraction in case when
frequency in subband placed just before Nyquist frequency.
Note: we still unable to handle situation with low frequency in
subband which reuired much more samples for analysis.
