55 Write mobility data

[HenrZu]

Changes and Information

Please briefly list the changes (main added features, changed items, or corrected bugs) made:

• Save data about the commuters during mobility
• Any Indices (or Groups of indices) can be chosen as input. Additionally, the total number of commuters is saved
• Additionally, it is possible to save only selected edges

If need be, add additional information and what the reviewer should look out for in particular:

• This functionality should be used carefully because if we save to many compartments from the edges, theres a large amount of storage necessary

Using the setup in our simulation with ~30.000 edges and 50 simulation days, the size of the Edges.h file is 135mb.

There is an inconsistency in our project between the use of the terms migrated and mobility. I would leave them here for now and edit this PR after merging so that we only use mobility.
