Need interface request definition for each event.

[SHaTRO]

We need Typescript interfaces for all the events.

Found some interface stuff in Golang at hekmon/plexwebhooks which was a start but it was essentially very limited.

Going to use the parsed analysis from Issue #3 to supply the data we need.

In preparation for release 1.0.0, we'll just put "any" on the interfaces we cannot define. Not ideal, but that is life in the fast lane.
