Split feature for preprocessing.py

[edgark31]

• Created a function in Utils to split train val and test sets so that both YOLO and RetinaNet models split data the same way
• Creation of JSON file to represent the split
• Modified preprocessing file to use JSON file if exists

Created a function in Utils to split train val and test sets so that both YOLO and RetinaNet models split data the same way

A long time ago, we had functions that did this in AxonDeepSeg. Maybe there might be some useful insights in those old files too:

Thank you! I'll take a look at them and talk to @hermancollin about it and the other changes
