This change adds blobs with +16 dB gain for a number of 20 - 100 Hz high-pass blobs. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>
Add of these blobs offers more flexibility to adjust the microphone capture sensitivity for a fixed gain endpoint. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>

Pull request overview
This PR adds configuration blobs for EQ IIR filters with +16 dB gain at various cutoff frequencies (20 Hz, 30 Hz, 40 Hz, 50 Hz, and 100 Hz) for both 16 kHz and 48 kHz sample rates. The configuration files contain binary data representing second-order high-pass filter coefficients generated by an Octave script.
Changes:
- Added 10 new IIR EQ configuration files for high-pass filters with 16 dB gain
- Updated the Octave script to include 16 dB in the gain list for automated generation
