Feature functionality
The current (#1218) implementation of ht.fft.fft() is only distributed if the input DNDarray is n-dimensional (n>1).

Research suitable algorithm and implement distributed 1-D FFT of 1-dimensional signal. (This will also allow to cover the case of a n-dim signal which has to be transformed along its split axis without the possibility to resplit, e.g., because the remaining non-split dimensions are too small to be split)
