WIP: Update tap

[Qard]

What does this PR do?

Update tap to help eliminate dependency on nyc.

Motivation

NYC is built on istanbul which was abandoned years ago. It has some dependency vulnerability warnings which will never be resolved.

Additional Notes

This is still a work-in-progress. Tap 18 seems to have made some significant changes in the rewrite in which they eliminated the nyc dependency. Lifecycle hook functions no longer accept a done callback, only sync or promise-returning forms now. Hooks trigger not just around tests but around describe suites too which results in sinon failures when we use describes recursively as it tries to patch already patched functions and then crashes.

I'm working on figuring out ways to resolve the behavioural differences without needing to rewrite all our tests, though I'm not yet sure how to deal with the describe nesting problem. 🤔
