Merged requested to merge optidata_management into develop
This feature branch introduces a new data type for simulated gridded optidata. The writeoutCounter moves from the observed datatype to the simulated datatype. In general it is very similar to the datatype for the observed gridded optidata.
In addition it contains some procedures that improve readability and reduce sources of errors. A bugs was removed where the average_counter was incremented dependent on how many optidata where simulated. This is now part of the new type.
