[APP][Pro] Beacon - Detect your presence with BLE beacons

I’ve just released v1.2.0 in the alpha channel. This release is compatible with Homey 2.0.0-rc2. There are some issues with the FlowCardTriggerDevice not triggering.

Only the cards work:
| Global | A beacon detected state is changed | (beacon name, detected) |
| Global | A beacon is inside range | (beacon name) |
| Global | A beacon is outside range | (beacon name) |
| Global | A beacon has been discovered | (beacon name, uuid) |
