add case in visualization routine: in measurementData file, if same simulationConditionId, but differing preequilibrationId etc.

[erikadudki]

in file 'get_data_to_plot.py', see ll. 92-102
TODO: Here not the case: So, if entries in measurement file: preequCondId, time, observableParams, noiseParams, observableTransf, noiseDistr are not the same, then -> differ these data into different groups!
now: go in simulationConditionId, search group of unique simulationConditionId
e.g. rows 0,6,12,18 share the same simulationCondId, then check if other column entries are the same (now: they are), then take intersection of rows 0,6,12,18 and checked other same columns (-> now: 0,6,12,18) and then go on with code.
if there is at some point a difference in other columns, say e.g. row 12,18 have different noiseParams than rows 0,6 the actual code would take rows 0,6 and forget about rows 12,18
