Implement a propagation module inducing charges using the weighting field

In order to properly simulate radiation damage and time distributions (very detailed), we need a new InductionPropagation module which, instead of "collecting" charge carriers does

• read a weighting field for one pixel in addition to the electric field
• calculate the integral of this field for every time step
• calculate the induced charge on the pixels above and around (configurable)
• outputs a charge-over-time distribution per pixel (probably in the same format as now: charges which timestamps attached)

Then, radiation damage models can be implemented by

• providing a list of traps with their probabilities
• checking after every time step these probabilities and trap charge carriers

This is not meant for v1.0 but as notes for a future project to be tackled after the release.
