[New exercise]: two-fer

[meatball133]

I implemented an exercise, you can use this for testing.

It did not work for the test-runner, don't know why. Also, there has to be a way for the test runner to not need to give function arguments.

About the list of arguments, did you try adding an empty list?

const TEST_CASES = [
	{"test_name": "Test Something", "args": [], "expected": "something"},
]

I haven't tested it yet, but the args get passed to the callv method in Godot, and I would expect it to work with an empty list. However, methods like this often have some issues ;)

The CI is set up now so I'd suggest rebasing. The test suite needs to be updated to the new spec. For that, you could look at the leap implementation.

@meatball133 could you please let me know what is the status of this exercise? The format of test suites has changed, so that part needs to be updated. Also, we agreed on using 1 tab instead of 4 spaces. Do you need any help with these changes? If you're overwhelmed with other tasks, I can take care of this one :)

Test methods need to start with test_ for the new test runner to pick them up ;)

It is also a standard in GDScript to have 2 empty lines between methods.

Other than this, I think the solution and tests look good 👍

Code good, tests passing ❤️ Thank you for your contribution @meatball133 ! :)
