Decklink: support display mode/pixel format combination that use padding.

Previously, the VideoDeckLink module was rejecting combinations of
video modes and pixel formats that cause padding. For example HD720
(1280 pixels per line) and 10BitYUV (encodes by blocks of 48 pixels) =>
16 padding pixels at the end of each line.
This format is now accepted and the padding pixels are sent to the BGE.
It is sufficient to edit the UV map so that these pixels are not displayed.
