Seppo Ingalsuo bede56972c Tools: Tune: TDFB: Updates for array geometry helpers and add 3D array 
This patch adds the missing XYZ 3D array helper and does minor fixes
for two others. The L-shape microphones orientation is made similar as
in rectangular array by inverting the y-axis. The missing centering
of rectangular array is added.

Seppo Ingalsuo d9de74b231 Tools: Tune: Add TDFB configuration tool 
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.
