Add Notification Access

[pbulsink]

It would be convenient to have API access to notifications, either by streaming (https://docs.joinmastodon.org/methods/streaming/#notification) or directly (https://docs.joinmastodon.org/methods/notifications/). This would simplify the creation of interactive applications (i.e. responding to a mentioning status, interacting with users who favourite/reblog, etc.).

@pbulsink: The return is a bit more complicated then the standard API output. But if you need it right now, you can use an unexported function:
rtoot:::process_request(path="/api/v1/notifications",params=list())

with the new generic function:
rtoot(endpoint = "api/v1/notifications")

Not going to add this due to complex return structure. If needed, please use the generic rtoot(endpoint = "api/v1/notifications")
