Move lib/rocketamf -> lib/rocketamf_extensions, to fix reload issues

Something in the Rails loader doesn't like that I have both a gem and
a lib folder named `RocketAMF`, I think? It'll often work for the first
pet load request, then on subsequent ones say `Envelope` is not
defined, I'm guessing because it scrapped the gem's module in favor of
mine?

Idk, let's just simplify all this by making our own module. I feel like
this old lib could use an overhaul and simplification anyway, but this
will do for now!
