Create a script that parses the output json and formats it for LLM input

[mhasoba]

It would be nice to have a script that will (per student, possibly further per assignment) output a string containing:

1. The student's code
2. The stdout from running it
3. The stdout from the linter
4. The student's log for that week
5. (Maybe eventually the assignment spec)

This can then be fed in as part of an LLM prompt to start testing automated personalised feedback.
