[Enhancement] Addition of Libraries to Places Tab

[Garfield96]

Is your feature request related to a problem? Please describe.
The details page for a place, e.g. "Garching Forschungszentrum", currently provides information for cafeterias and study rooms. The old TUM Campus-Android app also showed information for libraries. This would be really useful to for example check the opening hours.

Describe the solution you'd like
Include libraries similar to cafeterias and study rooms in the place details view.

Describe alternatives you've considered
None

Additional context
None

Libraries are fetched via the /openingtimes endpoint, this is not yet implemented in the new backend. I therefore marked this issue as blocked
