Imported unicode_literals and changed a few if statements to get a BE ODF translation + SHO guess to work

Setting the default parallel mode in the model to False if the number of cores turned out to be 1. No point creating the pool

Removed uiGetFile and corresponding PyQt5 dependency since it is VERY difficult to install PyQt5 on cades

Cnms dev

New win_data_func that returns the input image in the windata32 format
Use the data only mode if an invalid win_fft is given.

Removed import of the unicode_literal for all files. This will be added back only when h5py is fixed.

Changed how we define custom dtypes to work when import unicode_literals from __future__
