1342	Atoms.aniso_u(6) hides data	Tristan Croll	Tom Goddard	"Would be really good to have these carry through to the output PDB when they're present.

Related: at present, `Atoms.aniso_u` and `Atoms.aniso_u6` both return None if any atom(s) in the list don't have ANISOU records. The default behaviour in other packages seems to be to instead provide an array with the entries corresponding to non-anisotropic atoms filled with NaN. I guess there are arguments either way, but it seems counter-intuitive to return None where (some) data actually exists."	defect	closed	moderate		Core		fixed						all	ChimeraX
