Christophe Favergeon 1d9e38adca Reworked FFT initializations to make the work of the linker easier. 
New FFT initialization functions to make it easier for the linker
to optimize the code size when the library is used as a static
library and can't be rebuilt.

Compilation directives for code size optimizations have been removed.

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.
