Wishlist: Remove Kotlin Dependency

[vladaman]

We don't use Kotlin so removing this unnecessary dependency would decrease package size and project complexity. For libraries we prefer to stock with pure java.

This plugin has been abandoned now. Although there will be a package for beacons in Fuchsia repository in 2020.

If you want, you'll have to learn the native way and do Platform channels in AltBeacon.
