There is not any algorithmic changes in this version.
However, I made the following changes to make Python
and Docker installations better:
1-I changed base ubuntu from 20.04 to 22.04.
2-dssp 4.0 in Ubuntu 22.04 have a shitty requirement
 of CRYST record in the pdb file. Therefore, I manually
 installed dssp 3.
3-I needed at least Python 3.9 for importlib.resources
  and I made the required changes both in setup.py and
  Dockerfile for that.
