Christophe Favergeon 8092cc61f9 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.

Christophe Favergeon 8fb55a90b7 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.
