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.

+                   It is the reason for the arrays filterPos and filterLengths.
+
+                   window coefficients can describe (for instance) a Hamming window.
+                   The array has the same size as the FFT length.
+
+                   The folder Scripts is containing a Python script which can be used
