Updates to support Geocaching Home Assistant integration feature upda…

…tes (#23)

* Fix missing async keyword, see home-assistant/core#99977

* Add nearby caches to status

* Change trackable distance traveled data type

* Fix missing status initialization for nearby caches

* Fix typo causing cache coordinates not to be parsed

* Added update_caches and _get_cache_info, with some more stuff, have not been able to test that it works yet, /Per&Albin

* add seperate call for geocaches

* Started working on the trackable journey list, not yet tested /Albin Per

* fix for appending to array in trackable journey api

* add support for trackable objects

* uncommented code

* Revert formatting

* Fix errors and add missing cache data points

* Rename caches -> tracked_caches

* Correctly parse location data for caches

* Rename caches_codes -> cache_codes

* Fix trackable parsing, add additonal fields to caches and trackables, some refactoring and cleanup

* Formatting

* Always return original value if new value could not be parsed

* Update NearbyCachesSetting

* Rename cache update function

* Replace cache find count with found date and found switch

* Rework foundByUser to be nullable

* Fix nearby caches update condition and limit take parameter for API

* Remove unused function, align variables and functions to snake_case

* Improve trackable journey data and change API endpoint

* Reverse geocode trackable journey locations

* Add distance between journeys

* Handle blocking reverse geocoding outside of init function

* Separate nearby caches logic to allow directed usage

* Add comments and improve documentation

* Add settings validation method

* Add cache and trackable URLs

* Formatting and cleanup

* Update test

* Limits: cache and trackable limits in settings and in API call. Error handling: Raise error if too many codes were configured in settings. Automatically remove duplicate codes

* Move limits to limits.py
