Add message SIMID:Creative:requestChangeMediaURL

[davidthibault]

Would it be possible to create a message from the creative to the Ad player to ask to change the Ad media source (typically for multivideos linear Ad purpose).

For example :

SIMID:Creative:requestChangeMediaURL
The creative requests an ad media url change by posting a SIMID:Creative:requestChangeMediaURL message.

dictionary MessageArgs {
  required string uri;
};
uri, The address of the video media file

resolve
By posting resolve message, the player signals it has changed the video source url to the requested values.
reject
By posting reject message, the player signals that it did not change the video source url .

Thanks.
