Looks good on the whole!

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.

The implimentation looks good to me in regards to plan creating syncronization and execution interleaved and planner, all tests are passing and has good spec coverage. approved

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
