Issue:
Switch to tarpaulin for coverage
Up to this point `cargo kcov` has served us fairly well, but it's been causing some problems of late that aren't terribly surprising considerking that kcov's primarily focused on C/C++ code. We've notably had incorrect coverage reports on things like functions w/implicit expression returns and it's convinced me it is time to switch. 

I've already done some local and CI testing with tarpaulin and confirmed it's working well (including the cases kcov was having challenges with) and believe that's the way to go.
