1229	Eliminate is_het res attribute	Eric Pettersen	Eric Pettersen	is_het is format specific and should be handled by the appropriate bundles.  To eliminate it, need to move PDB-specific connect_structure() from atomic into pdb bundle and implement generic replacement.  Also need to have mmCIF write HETATM for non-standard residues and pdb do the same except also take optional list of non-standards to write as ATOM.	enhancement	closed	blocker		Core		fixed			1230	1228		all	ChimeraX
