Organize report by function arguments

[impguard]

How hard would it be to add different display options to organize the final report? As of now it's organized by each function call, but it would be nice to see a report broken down by function arguments.

Say I write a test suite calling function foobar with a bunch of different arguments, it would be nice to see how well that function scales depending on what's passed to it. Right now the only way to do this is to write a bunch of separate tests and run each in isolation. This is particular clumsy with hardhat mocha as well because running a single test is not easy from the command line.

Would be nice to be able to run the whole suite and see a detailed report of function breakdown by args. Other possibilities are to have a report breakdown per test function vs. for the whole suite (though not sure how easy it is to split metrics that way).
