Vendor Jason library (#258)

* Vendor Jason library

Vendor the Jason library so that the version of Jason used by ElixirLS does not
conflict with the version used by the end-users code. Right now one will win out
over the other which can lead to issues. Luckily since Jason has been pretty
stable there haven't been too many issues up to this point.

Fixes #253

* remove jason from mix.lock
