[APP][Pro] BeNext - BeNext devices for Homey

The BeNext App is now updated to SDK3 in the test:

I would be happy if people would test this, since i only have the window sensor.
And yes, that one works fine, and i didn’t need to fix that one special.

So, i expect all drivers to work, except perhaps the 500 tag reader, since that once is buildin completly different.

Let me know if you run into issues!
