Subject: [PATCH] Replace `poison` dependency w/ `jason`

The dependency took a long time to compile, and was causing problems for
a user who was attempting to build the project.

Since it wasn't a strictly necessary dependency, and `jason` was already
included in the project, all instances of `poison` have been replaced
with `jason`.

The only additional code that this introduced was converting from
generic maps returned by `Jason.decode` into Service structs.
