UltraHDMI update

From Marshal: HW2 Analog RGB expansion board with Deblur for RGB is working! Maybe you could ask people if they care one way or another about component Y/Pb/Pr output and if they want gamma correction on those outputs. It’s possible, but takes more work.

Again this is for HW2 only. (Hard Ware revision 2) Cost will be the same for main board, but I don’t know how pricing on the analog plugin board will go. It will have another flex to run to the Multi-AV connector.
