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.
