can you explain this change ?

The tests were failing and this was a way I found to make them pass. I can't really do much about increasing the accuracy of the rocfft results.

Description
Add rocFFT as a backend for the DFT interface, allowing use of the DFT interface with AMD GPUs.
There is a bit of a issue with
rocfft_setup/rocfft_cleanup. These both affect the global state, so if the user was also using rocfft (unlikely), they could potentially cause a "double" setup/cleanup.Fixes #27
