FFT in MIPS implementation is working iteratively instead
of "recursively" calling functions for smaller FFT sizes.
Some of DSP and format convert utils functions are also optimized.

This allows cleaner implementation of other psymodels using the existing
structs. It also will make it easier to interchange individual parts of
