Runner Module for running SMIET

Issue

While the method to use SMIET is relatively simple (make_template -> map_template), the methodology requires one to use

• several origin showers based on xmax and zenith ranges
• using interpolated synthesis, which is most recommended to remove the bias
• filter the trace from the sliced / coreas showers and compute the fluence every time to check and return meaningful results

To alleviate these problems, I propose to generate a general SMIET class that will do all of this with a single class. This will

• set up a site and backend
• generate templates based on the origin library
• load templates based on origin library
• setup target showers, either based on given longitudinal profile or coreas showers
• synthesise (interpolated) for each of them, in star shape
• return the traces (filtered already in the relevant range) and fluences
