Change run scripts that take EPC data as arg to use preprocessed EPC

[crispy-wonton]

Currently, run scripts need to be run in a certain order with the output of the previous run script acting as input into the next run script. This makes it confusing to know which processed version of EPC is required as an input for each run script.

I suggest we change the pipeline so that each separate script outputs the required data only, and then in calculate_suitability.py all the separate outputs are loaded and merged into one dataset to calculate suitability scores.
