7564	Handle 5-character residue names from Protein Databank	Tom Goddard	Greg Couch	"The PDB announced the will switch from 3 character to 5 character residue names by 2024, possibly sooner because they will run out of 3 character names.

I'm not sure if any of our code will need fixing for this.  I think we handle residue names of any length.  But I am not sure whether our Chemical Components Dictionary (CCD) fetching code makes any assumptions about 3 character names.  Also might be worth checking of the Chimera mmCIF reader handles the 5 character residues names."	enhancement	closed	moderate		Input/Output		not a bug		Eric Pettersen				all	ChimeraX
