Implement type safety and type definitions on the events

[jcodog]

Work on making this fully compatible with typescript including some type definitions for the data, so that it can be incorporated into typescript apps running on nextjs.

Being able to access the connector.on("chat", (data) => console.log(data)) is great, but being able to see all the possible returned options on the data object from the chat event would be massively helpful for working with this package.

Instead of manually defining the types of the events used every time this package is implemented into a typescript app. Some apps are failing to compile due to lack of type definitions from this package.
