Fixes #5806 Implemented "Refresh" button to clear the cache and reload the Nearby map (#5891)

Browse source 
* Changed files required to get the app to run correctly. Removed suspend from affected DAO files and funcs, and changed to (Kotlin v1.9.22) and (Kotlin compiler v1.5.8)

* Created refresh button icon, and added it to the nearby_fragment_menu.xml (header of the nearby page). Created function refresh() in NearbyParentFragment.java to handle refresh functionality.

* Replaced refresh() func with emptyCache() and reloadMap()

* Attempt at reloadMap(), no testing done yet.

* added changes for a possibly working emptyCache implementation (needs testing).

* Tested changes as working, edited emptyCache to correctly clear cache and then reload map
