Execute real DFT on in and write the result to out

Parameters
plan	Pointer to the DFT plan.
out	Pointer to output data. May point to the same memory as `in` for in-place execution.
in	Pointer to input data.
temp	Temporary (scratch) buffer. If `NULL`, scratch buffer of size `kfr_dft_real_get_temp_size_f**(plan)` will be allocated on stack or heap.

Note

This function reads \(N\) real values from in and writes \(\frac{N}{2}\) (Perm format) or \(\frac{N}{2}+1\) (CCs format) complex values to out, where \(N\) is the size passed to kfr_dft_real_create_plan_f**.
