Disable parsing of nested_flatbuffers as bytes by default

Browse Source 
Parsing as bytes produces buffers that are unsafe to access unless passed thru a verifier,
whereas users could reasonably assume that any JSON parsed without errors is safe to access.
Users that still have legacy JSON files with such bytes in it will get a helpful error point them
to the option to turn on to have it work again.
