Option to run specific Unity test function

Related: ThrowTheSwitch/Unity#611

Within my project, I have many test functions. When one fails, finding out which one is tedious. Unity has command line support (when UNITY_USE_COMMAND_LINE_ARGS is defined) through it's -n or -f arg, but I couldn't see how to pass args to Unity via pio. The test_filter option in the .ini isn't useful in this situation, because it filters on test library, not test function.

Idea: Provide a way of filtering by Unity test function, or maybe have a way of passing args to Unity.

Thinking about it a bit more, I'm guessing this would need changes/improvements in the Unity library?

Also, perhaps Unity could be improved by showing a list of failed tests in the summary at the end (so you don't have to hunt for failed tests in the log). Certainly an issue to raise in Unity there.

Edit: Raised new issue in Unity: ThrowTheSwitch/Unity#611

Will #3132 help you to solve this issue?

Yes thanks, I'll close and add to that issue.
