Add support for DSSP version and add rsa node features to residues with insertion codes

[biochunan]

Reference Issues/PRs

Fixes Issue #353
Fixes Issue #354

What does this implement/fix? Explain your changes

For Issue #353, this PR added a line to determine dssp version, which is passed to the function Bio.PDB.DSSP.dssp_dict_from_pdb_file otherwise, biopython will use default version number 3.9.9 and for users with dssp version >= 4.0.0, this will lead to an empty dssp DataFrame

For Issue #354, this modification fixes errors caused by missing rsa feature from nodes with insertion code. This is caused by skipping insertions when creating node_id. This modifications adds insertion codes to node_id if insertions is set to True in ProteinGraphConfiguration.

What testing did you do to verify the changes in this PR?

Added a script test_dssp.py to tests/features
The example input pdb file (with cryst1 line and insertion codes) is attached here: input_pdb_cryst1.pdb.gz

File with suffix .pdb is not supported by GitHub, thus the compressed version. Need to uncompress it first before running the test.

Pull Request Checklist

• Added a note about the modification or contribution to the ./CHANGELOG.md file (if applicable)
• Added appropriate unit test functions in the ./graphein/tests/* directories (if applicable)
• Modify documentation in the corresponding Jupyter Notebook under ./notebooks/ (if applicable)
• Ran python -m py.test tests/ and make sure that all unit tests pass (for small modifications, it might be sufficient to only run the specific test file, e.g., python -m py.test tests/protein/test_graphs.py)
• Checked for style issues by running black . and isort .

Thanks @biochunan LGTM! Only comment re: pdb files - I'm quite sure these can be uploaded uncompressed. See: https://github.com/a-r-j/graphein/tree/master/tests/protein/test_data

LGTM. Will merge once tests pass. I think uploading the PDB (or using an existing file in test_data/ should work).

[a-r-j]

On second thought, it's likely the .gitignore that's preventing you from adding the .pdb file. Try: git add input_pdb_cryst1.pdb --force.

Hi @a-r-j thanks for going through the PR.
For the pdb file, I was trying to upload it through the PR window and GitHub doesn't support files with the suffix pdb.
Will use existing pdb files in ./test_data in the future.

[biochunan]

I had a look at the three pdb files in tests/protein/test_data, and they do not have insertion code. Maybe it's a good idea to add a PDB file with insertion codes for insertions related testing.
