clfft on CPU segfaults on 16384x16384, so this PR also adds restriction to complex transforms
- the clFFT doc only talks about real transforms, so numbers for complex case have been derived by testing (clFFT on CPU is more experimental as devs focus on GPUs)
Readme includes cmake version hint (see PR #118 )

thanks a lot
