Advance version number to 1.43.0

Because as it turns out, WiFi network suggestions cannot be removed
by the user. Which is pretty silly in my opinion. But anyway, now a
user can remove all the networks added by Binary Eye.

-At the time of writing, calling `RenderScript.forceCompat()` in a build made
-on macOS Catalina with build tools 29.0.3 will crash the app. This is a bug
-in the build tools for Catalina.
+If you want to fork this and are only interested in reading 2D barcodes
+(like QR or Aztec), you may want to remove the custom rotation kernel
+altogether as ZXing can read 2D barcodes in any orientation.
 
-So *do not* build release builts on macOS Catalina with build tools 29.0.3.
-
-Building on Linux with 29.0.3 works fine.

-### App Bundle

-At the time of writing, `./gradlew bundleRelease` will produce a broken
-App Bundle without the necessary RenderScript libraries. This is another
-bug in the build tools.
+This will make your app a bit simpler and saves you from compiling a
+custom RenderScript kernel for each architecture you want to support.
