Added EXR support

[Jerry-Master]

The run.py now can read EXR files and write EXR files. It creates an extra folder for saving the EXR with float32 precision, which are ready to be used in current VFX pipelines. It also clamps the input to 0-1, a more interesting approach may be to use logarithmic color space but that is shot dependant so I did not include it.
