Let elixir handle protocol consolidation

[starbelly]

It seems as though we can simply let elixir and friends handle protocol consolidation which resolves issue(s) in pulling in deps such as Jason, Decimal, etc.

1> 'Elixir.Jason':encode('Elixir.Decimal':new(<<"1.0">>)).
{ok,<<"\"1.0\"">>}
2>

It may be there is a piece to the puzzle here I'm not understanding about protocols and releases and why it needs to be handled the way it is. If this is not the case, I'll happily add a test case to go along with this change.

@starbelly as far as I know this is not consolidating the protocols so is not what anyone would want to use in production. It technically works, but is slow.

Closing this per misunderstanding of protocol consolidation on my end.
