ESMProtein.from_pdb() ignores HETATOM

Hi,

I'm currently working with your  ESM3 model and create embeddings with pdb-files. 

The problem is: ESMProtein.from_pdb() ignores HETATOMs, which are in my case essential (E.g. modified AAs, DAAs etc). Would be nice to have a flag or sth to include the HETATOMs in the processing.

Thanks in advance (:
