Generate cytoscape session files manually

[tristan-f-r]

Our cytoscape visualization is slow and incredibly flaky, with a retry system already built in that fails to work sometimes. [Assuming that its possible,] it may be better to build the file manually.

This would also close #171 if implemented.

Our Cytoscape session file is not very robust. However, the motivation for supporting this is that some of our existing use cases require loading 100s or more pathway graphs into Cytoscape. Doing that manually requires clicking through the Cytoscape menu, selecting a file to import, and loading the pathway graph for each individual file, which is quite tedious.

Ah. I should have worded the issue better:

We can recreate the session files in SPRAS 'manually' (programmatically).

I looked into this more, and the session files don't have good documentation, so this would only be good to do possibly when an external library appears for cystoscope that doesn't rely on CyREST, and thus cytoscape.

That makes more sense.

The Cytoscape documentation is part of the reason it was hard to get a stable container working in the first place. It was a lot of guess-and-check and asking questions on their discussion board to try to get one image that would work with Docker and Apptainer.
