fix: Remove ModelParser and move static functions to the respectful fragmentation class that uses them

[fvaes-cegeka]

As described in #1152, the former ModelParser class had static methods utilized by both the TimeBased and Geospatial fragmentation strategies. However, only two public methods were utilized, each by one strategy, and there was no shared code between the two strategies. Therefor the ModelParser is removed and the functions are relocated to the respective fragmentation strategies.

In addition, one test within the TimeBased fragmentation strategy required adaptation since it relied on a mock of the ModelParser class.
