DevicePoseProvider: improve getLocation() (#1454)

* Only take updated location when it is of better quality

* Rename to AndroidLocation for clarification

* be pedantic about licenses

* fix race condition in DevicePoseProvider.kt

* add possibility to explicitly skip cache upon requesting location updates for WeatherRepository.kt

* LocationsRepository.kt: use getLocation() in combineTransform() to properly wait for & update on new locations

* LocationItem.kt: fix getAzimuthDegrees() usage for userHeading
