This is a first PR to replace the dummy code in MSubModuleChargeTransport::AnalyzeEvent.
I will open this as a draft PR, there are still a lot of magic numbers in there (bias voltage, temperature, initial charge cloud size, cross-talk parameters), but this is mainly to collect feedback on my current implementation while moving forward and improving this in comparison with data.

Some mathematical background:
The linear charge density of an event at a given position and depth can be approximated by Eq. (7) in https://doi.org/10.1016/j.nima.2023.168310. To get to the actual charge/energy, we need to integrate the linear charge density from the left edge of the strip to the right edge of the strip:

The idea is then to calculate the energy for the main strip and it's direct neighbors.
Here is a plot of what is happening in the code:

The implementation of cross-talk is based on the parameterization that we obtained from simulations (for now just for one detector and implemented as magic numbers). This currently seems to underestimate the cross-talk on the HV side and overestimate the cross-talk on the LV side.
