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.
PythonWrapper was no more building on windows due to a too long
link command line.
A temporary fix was made. But on long term the wrapper must be refactored
into submodules to allow to more easily add new functions.
MFCC F32 implementation
MFCC F32 tests
MFCC F32 in Python wrapper
Python wrapper structure updated to support submodule like
cmsisdsp.mfcc and cmsisdsp.fixedpoint
PythonWrapper tests updated to use the new fixedpoint
cmsisdsp.mfcc is used to generate the mel filter, dct and window coefficients.
Solve most of f16 issues. But there are still some remaining
build issues with gcc10q4.
2 functions are reverting to scalar version when build with gcc on M55.
(Since Helium versions of those functions are not building).
The goal of this commit is to allow the build of CMSIS-DSP on Windows to
enable the use of the library from Python or Matlab.
The Python wrapper has also been simplified and is now using the
CMSIS-DSP directly without requiring specific include files or source files.
