avfilter/lut3d: fix channel order in Iridas format parsing.

According to http://doc.iridas.com/index.php?title=LUT_Formats

    for 3D textures, the data is also RGB, and ordered in such a way
    that the red coordinate changes fastest, then the green coordinate,
    and finally, the blue coordinate changes slowest:

Fixes Ticket #3236.
