TopologyReader currently fails to build more than 62 proteins, since it tries to assign a unique chain ID to each one, and these are currently limited to a single character (upper or lower case A-Z, plus 0-9) to support PDB output. Allow assigning multi-character chain IDs, at least when only RMF or mmCIF output is needed.
