Accept signals of any length
Created by: waddafunk
Is your feature request related to a problem? Please describe. Right now the transforms accept only signals with a length equals to a power of two.
Describe the solution you'd like Generalize the transforms to signals of every length. This can be easily done by zero-padding the signal to the closest, power of two lengh > signal length before executing the transforms.
Describe alternatives you've considered User can perform zero padding himself and transforms can be left as they are.
Additional context Nohing to declare here.
