HDR Info passed to Kodi

[mcarlton00]

I can definitely add that (unless somebody else beats me to it). Looking at the source from upstream it should be fairly easy to add, but I don't have any HDR content or devices capable of playing them, so I might have to fake it for testing purposes or get some help once I get to that stage.

I've just been busy with IRL things and haven't had much jelly dev time lately, and when I have had time it's mostly been spent writing tools to help combat the spammers. I'll get to it sooner or later.
