This patch adds the tool for creating beamformer configurations. The
microphone array geometry and beam angle (azimuth, elevation) need
to be specified. See the example scripts and sample array helper
functions.
The FIR blob quantize function needed a minor change to prevent strip
of trailing zero coefficients. The beamformer filter bank needs to use
equal length filters.
