Move FFT functions and blocks to templates (#3903)
* fft: refactor fft classes as templates In order to reduce code duplication construct fft objects and blocks with template paramters. Separate forward and reverse as a template parameter Maintain the real fft block forward as r2c and reverse as r2c as well Co-authored-by: Andrej Rode <mail@andrejro.de>
