pulling in the erlang sdk client so I can compare results

I'll need to tweak this a bit to allow it to load configs from a file
like I have things setup for testing with this elixir version, but this
will let me run a bunch of tests to compare results of the two to ensure
we have exactly replicated functionality. it'll also make it a lot
easier to confirm that I've fixed the crashing issues that might exist
in the erlang version
