DataInterpreter: Add visual hex color interpretation
It would be nice if the DataInterpreter could display a visual color of the selected block values (needs #213 first). E.g. on three selected blocks RGB and on four RGBA (maybe ARGB alternatively). Alternatively (or additionally) a color name could be displayed to give a hint but visual is better I would say.
How a similar thing looks in Imhex (with mouse pointer over the RGBA8 color):
In this case it just takes the next four values from the cursor position. Guess this is just simpler anyways than having to select four blocks.
Since data interpretation section became enormous with addition of date-time section that enabled at last trunk, might be it's good to have a options dialog to customize which values gonna how than allow RGBA8 and RGB565 color selections.
