Closes #467 #649. I have no evidence that moving .cpu() improves performance on predict step. I was not able to decipher what is happening with more than one gpu within predict_tile. I compromised and added a warning and set to one gpu, then added a doc that gave some general outlines on how we use dask and SLURM to parallelize.
