JSC wasn't the cause for the crash we were hunting after all. RN doesn't set
HErmes as the default, neither does Expo, so the jury is still out on Hermes,
and it looks like JSC is still the safest bet.
In addition, the way Hermes is packaged (as a standalone AARs, instead of a
local "Maven repo") complicates the SDK build and can make the resulting build
bloated.

I removed this, because RN has updated the builtin JSC version. On the next
release, however, RN introduced a new JS interpreter (Hermes) so JSC is now a RN
dependency. Thus, add the magic spells to publish the AARs to Maven.
When running the app from Android Studio the React packager is not automatically
started. In vanilla RN projects this is done by the "react-native run-android"
command, but often times it is desired to run from Android Studio.
This fixes that by starting the packager from Gradle.
