rna_pdb_tools.py -- TypeError when running --edit option

[mjustynaPhD]

When running a command: rna_pdb_tools.py --edit "A:1651-1656>A:1-6,A:2004-2006>A:1-3" pdbs/7RQB_1_1A.pdb I encountered the following error:

Traceback (most recent call last):
  File "/home/marek/anaconda3/envs/rna-tools/bin/rna_pdb_tools.py", line 844, in <module>
    output = edit_pdb(f, args)
             ^^^^^^^^^^^^^^^^^
  File "/home/marek/anaconda3/envs/rna-tools/lib/python3.12/site-packages/rna_tools/rna_tools_lib.py", line 2012, in edit_pdb
    output += edits
TypeError: can only concatenate str (not "list") to str

I did some debugging and fixed the issue, but unfortunately, I have no permission to publish a hotfix branch or create a PR. The problem is with the line indicated in the error (rna_tools_lib.py:2012). I think that this might be an artifact from the past. The easiest fix I found was just to remove this line (output += edits), as it's not needed.
I think that you wanted to keep the command in the output file, but it is actually already added in line rna_tools_lib.py:1999.

dear @mjustynaPhD can you send me this pdb file?

I see that edits could be combined.

Can you run this edits sequentially, I'm not sure if you can do two edits at once (I have to look into the code, this should be in the documentation, sorry for missing this information)
rna_pdb_tools.py --edit "A:1651-1656>A:1-6" pdbs/7RQB_1_1A.pdb > a.pdb
rna_pdb_tools.py --edit "A:2004-2006>A:1-3" a.pdb > b.pdb

OK, there was a stupid typo in the code, I'm not sure why it was there. It should work now with GitHub or 3.20.2
