simple enough, I'll do that

Ok, I'll move it outside the if

yes this is a bit messy, mxfdec puts the reel_names on streams. Even if
the all the streams source the same reel package, I'd like to try and fix
that in mxfdec and put them on format level. How about for mxfenc being
strict and only accepting reel_name metadata at the format level for now?
