Add caching to DB

[grine4ka]

To avoid rapid API requests (not to overcome quotas) we need to cache data about teams and venues.

It's a good practice to update teams once a day (not more rapid).

Updating once a day

Store date of last update to some preference and check it every time you try to get teams.

Alternatives for using dates: https://medium.com/nanogiants/handling-dates-on-android-1fccccde9d54 I can work with date using this library: https://github.com/Kotlin/kotlinx-datetime
