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.

Fix - arm_math.h: Use the float suffix in arm_clarke_f32
...
The float suffix replaces the need for a float cast in arm_clarke_f32.
This change is necessary to avoid large amount of warnings by arm_math.h when the -Wunsuffixed-float-constants flag is used. And using this compile flag is very reasonable on a processor with 32bit FPU.
