Get rid of GMS dependency

[12people]

Is your feature request related to a problem? Please describe. Not all Android devices come with Google Services support and some open-source app repositories strictly prohibit integrating proprietary packages like it.

Describe the solution you'd like It'd be great if this package could get rid of its dependency on Google Play services — specifically 'com.google.android.gms:play-services-vision.

i don't think it can be done that easily. the camera handling, logic of detecting bar- and qr-codes is in that package. removing this dependency is like taking the engine out of the car.

@BjWe to help your imagination grow - see plenty of other cars without engine which work very well scanning QR here: https://search.f-droid.org/?q=qr&lang=en
