Non-deterministic weight for HPC points

[khelfen]

Currently, the HPC points are given a random weight for assigning charge events. The input data would allow a deterministic approach as a potential is given within the dowloaded GPKG data from zenodo. The HPC function, unlike all other use cases, does not allocate the energy_sum to the charging points and therefore the information from the potential column is not used later. This should be changed by either distributing the energy_sum according to the potential column or using the weight of the potential column directly.
