Fix crash when disabling Basic Mode - enable Jetifier

The GraphView library (v4.2.2) used in fragment_osdalg depends on the old
Android Support Library (android.support.v4.widget.EdgeEffectCompat).
When the fragment is inflated, this causes a NoClassDefFoundError crash
since the app uses AndroidX.

Enabling Jetifier automatically converts old support library references
to AndroidX equivalents at build time, fixing the crash.

Fixes #251
