Add support for Plex Profile Watch History and Ratings

[simonc56]

What is your feature request?

With the Activity feature added to Plex, user can see its own Watched History and Ratings.

• https://support.plex.tv/articles/profile/
• https://app.plex.tv/desktop/#!/profile

It would be great to be able to leverage this feature with Plexapi and have commands to get last n watched items or last n rated items from Plex account.

Additional Context

The Plex web app seems to request the server like this (example for last 50 watched items) :

POST https://community.plex.tv/api

{"query":".........",
"variables":
{  "first":50,
   "uuid":"......",
   "skipUserState":true},
   "operationName":"GetWatchHistoryHub"}

+1 for this addition. At the moment I use some custom Python alongside this library to extract this code but it is a messy integration.
