Donkie e71e7cbbe2 Added a standardized json unit test results log and added my vscode test runner to recommendations (#56058)
Link to the test explorer: https://marketplace.visualstudio.com/items?itemName=Donkie.vscode-tgstation-test-adapter

The test explorer adapter lets you compile and run the code in one click of a button, with no messing about with defines necessary

The extension supports reading test results from the unit test logs, but its shitty having to parse logs for that, so this PR also adds support for a somewhat standardized method of logging unit test results to a json file instead.

/*
Usage:
Override /Run() to run your test code
Call Fail() to fail the test (You should specify a reason)
You may use /New() and /Destroy() for setup/teardown respectively
You can use the run_loc_bottom_left and run_loc_top_right to get turfs for testing
