Support for dynamic test case outputs

[Yash-Singh1]

Some test cases can have multiple outputs such as https://cses.fi/problemset/task/1640. Currently, I believe that the judge doesn't validate dynamic outputs looking at the source code:

online-judge/submit/src/problemSubmission/createSubmission.ts

Line 307 in 74f57da

return given.trim() === expected.trim();

Also, submitting to it on one of my USACO Guide Groups gives me partial WA while CSES gives me all AC.

An idea to fix this could be replacing .out files for all problems with multiple correct answers and instead replacing it with an executable or other script file which would validate an output, and then automatically detecting a lack of a .out file in the actual grader code. Probably would have to start changing the code below:

online-judge/submit/src/problemSubmission/fetchProblemTestCases.ts

Lines 50 to 61 in 74f57da

	const regexMatch = file.Key!.match(/\/(\d+)\.(in|out)/);
	if (!regexMatch) {
	throw new Error("Failed to parse file name " + file.Key);
	}
	const testCaseNumber = parseInt(regexMatch[1]);
	const isInput = regexMatch[2] === "in";
	if (isInput) {
	testCases[testCaseNumber - 1].input = content;
	} else {
	testCases[testCaseNumber - 1].expectedOutput = content;
	}
	})

Changing the Error thrown to instead check for an executable/script file and then if found set the necessary parameters so it can be used during grading.
