Fix residence time save curve path; fix ligpargen url; fix connection not private

[htz1992213]

Summary

Include a summary of major changes in bullet points:

• Fix residence time save curve path
• Fix ligpargen url
• Fix "Your Connection is Not Private"

Additional dependencies introduced (if any)

• List all new dependencies needed and justify why. While adding dependencies that bring
  significantly useful functionality is perfectly fine, adding ones that
  add trivial functionality, e.g., to use one single easily implementable
  function, is frowned upon. Provide a justification why that dependency is needed.
  Especially frowned upon are circular dependencies, e.g., depending on derivative
  modules of pymatgen such as custodian or Fireworks.

TODO (if any)

If this is a work-in-progress, write something about what else needs
to be done

• Feature 1 supports A, but not B.

Checklist

Work-in-progress pull requests are encouraged. Please put [WIP]
in the pull request title.

Before a pull request can be merged, the following items must be checked:

• Code is in the standard Python style. The easiest way to handle this
  is to run the following in the correct sequence on your local machine. Start with running
  black on your new code. This will automatically reformat
  your code to PEP8 conventions and removes most issues. Then run
  pycodestyle, followed by
  flake8.
• Docstrings have been added in the Google docstring format.
  Run pydocstyle on your code.
• Type annotations are highly encouraged. Run mypy to type check your code.
• Tests have been added for any new functionality or bug fixes.
• All linting and tests pass.
