MATVT v1.0.7-pre

Pre-release with a fix for Android 12.

Update: cleaned up non adb versions. Future release will feature toggling between engines avoiding the need of two different Apks.

Update: added non-adb version APK as well for #61 (use the 1.0.7-pre2 version).

It has quite a lot of improvements by @aquirozc (especially around scroll mode stability)
These will be included in the next stable release.
