Version 1.30

Version 1.30.1 is released!

This fixes a crash since 1.29 on some devices on startup (it seemed to be very rare, but apologies if it affected you).

Focus/metering regions and face detection now works properly with the Camera2 API when zoomed.

Otherwise, a few minor UI fixes/tweaks. Most notably, the "popup" button now uses the "three vertical dots" icon. This is a standard way on Android of indicating "more options", so hopefully it's better for new users.
