Create a standard plot for timeseries objects

[kilianvolmer]

Motivation / Current Behaviour

Currently, each time one wants to plot a timeseries, one has to write a new script.

Enhancement description

We want to have a standard script, part of the memilio.plot or memilio.simulation package, that plots a timeseries automatically. Ideally, this would take into account different age groups or regions automatically.
