Resolves #904

The previous logic worked really hard to copy into the destination image in pixel order, but was complicated and buggy. The new logic works in source byte order, which is much simpler. The interleave types now mostly reduce to different ordering of the for(...) loops. I expect this will be extensible to handle row padding and blocking, likely with shared code, possibly an inline function.

Also adds tile-component interleave decoding, with small samples generated by gpac uncvg.
