Updating tests for SGF-Parsing

Pull Request

Hello @kahgoh,

This PR introduces 11 new tests for the sfg-parsing exercise to align it with the problem-specification repository.

However, I encountered difficulties with getting the example solution to work, despite spending several hours trying different approaches. Please let me know how you would like me to proceed from here.

Hey @jagdish-15, I'll try to take a look at the example solution over upcoming week.

Hey @jagdish-15, I managed to get something working. If I'm not mistaken, I think there is are too many \ characters in the withinPropertyValueWhitespace test (I think this is the "within property values, whitespace characters such as tab are converted to spaces" test case from the problem spec?). I couldn't quite see what you tried with the example solution, but if needed, I got something working by adding some more state to track while parsing.

Thank you so much, @kahgoh, for guiding me through this! I apologize for the oversight—there must have been a mistake on my part while copying data from the problem specification repository. I likely copied it directly from the terminal when the configlet printed the tests before updating, and some discrepancy must have occurred during that process. That aside, I’m happy to report that all tests are now passing after your changes to the reference solution!
