[me-media-timed-events] Inaccurate description of cue enter/exit event limitations (#50)

chrisn has just created a new issue for https://github.com/w3c/me-media-timed-events:

== Inaccurate description of cue enter/exit event limitations ==
In section [5.2.1](https://w3c.github.io/me-media-timed-events/#using-cues-to-track-progress-on-the-media-timeline), the statement

> This method is only possible for cues created by the web application, i.e., VTTCue objects, and not cue objects created by the user agent.

is not accurate. It is possible for cues created by the user agent, in the case where the UA creates cues by loading a WebVTT resource using the `<track>` element, because application code can access the list of cues and add `onenter` and `onexit` handlers.

This point should also mention that the timing of `enter` and `exit` events varies between implementations, due to differing interpretations of _time marches on_.
