Added window functions for use with Fourier transforms.
...
Regular functions for use with tone detection and noise estimation.
Flat-top windows for estimation of tone amplitudes.
Parameters of the windows are given.
Kaiser window missing (Bessel function not available in the library).
No f16 implementation since it is not accurate enough. It is better
to compute a f32 window and convert to f16 after.

CMSIS-DSP: Improvements to pull request #1363
...
To avoid having to change the API in an incompatible way,
a arm_mat_mult_opt_q31 was introduced and is providing a faster implementation
to use with Helium (but requiring more storage for intermediate results).
Some improvements to tests for matrix functions added.

CMSIS-DSP: New MFCC Q15 and Q31
...
arm_cmplx_mag_q15 reworked to be more accurate but less efficient.
New function arm_cmplx_mag_fast_q15 introduced to retain previous
(less accurate) but faster behavior.
Improvement to Python wrapper to support the new functions.

CMSIS-DSP: Added MFCC F16
...
This first version is not very accurate due to problems with the log.
A coming commit will improve the log accuracy.
Issues #1305 and #1304 also corrected as part of this commit.
