Add support for preview images AdaptionSet/Representation in DASH

[pi-andrei]

To implement seek thumbnails, usually custom solutions of loading images is used. But there is a standard of defining seek thumbnail images in dash manifest. Please see this document: http://dashif.org/wp-content/uploads/2017/09/DASH-IF-IOP-v4.1-clean.pdf in chapter "6.2.6. Tiles of thumbnail images". Can ExoPlayer dash manifest parser add support for such AdaptionSet/Representation and provide method in player for getting preview image? Thanks.

Hello. Any update on this?
Can you maybe guide me, which classes I need to edit/create to make it work in some way?

I'd like to know if there's any way to do this now too (showing preview while seeking), please help. Thanks.

Also interested to get a status update and to evaluate how we can make it happen together as a community.
Maybe @marcbaechinger or @ojw28 would have a suggestion too.
