Bacterial Builder 3D SNFG icons

Report: AAT and Hep do not have 3D SNFG like Man or Kdo do.

Oliver: We need to add the additional residues to the list in the Mol* codebase. David Sehnal is the one to contact about this. See https://github.com/molstar/molstar/issues/437 for what to do.

Before we do this, we need a comprehensive list of what residues are missing icons and what those icons are supposed to be. Either find them here in Table 1: https://www.ncbi.nlm.nih.gov/glycans/snfg.html or discuss with a subject matter expert on what they should be.
