fixing backslashes, adding basic metrics

[SilenNaihin]

Background

Metrics are super important, making things better.

Changes

• default of 3 to get added to regression test, 1 to get removed (mocks don't affect either)
• fixing backslashes
• adding metrics for individual challenges (run_time, success_%), is_regression, highest_difficulty you beat overall,

    "metrics": {
        "run_time": "0.93 seconds",
        "highest_difficulty": "advanced: 5"
    },
    "tests": {
        "TestDebugSimpleTypoWithGuidance": {

                "success_%": 0,
                "run_time": "0.465 seconds"
