Subject: [PATCH] Updated add/removeEventListener typings

The add/removeEventListeners should accept a type that is defined by fscreen itself (6 possible string values instead of just `string`), and the  optional options parameter should be of type `boolean` or `AddEventListenerOptions` instead of `boolean` only.
