Add interval to async utilities to supplement post render checks

[mpeyper]

What:

Resolves #241
Resolves #393

Why:

If hooks don't render the checks don't run. This makes waiting for side effects or other changes outside of the hook's render lifecycle more difficult.

How:

• Replace wait with waitFor
• Introduces an interval option to waitFor and waitForValueToChange
  • check callbacks run after interval time if no renders have occurred since last check

Checklist:

• Documentation updated
• Tests
• Ready to be merged
  
• Added myself to contributors table
  

I'm having some issues generating the docs to check the changes there. There appears to be an issue with one of dependencies of docz but I have yet to look into it more closely. These seems to only be an issue locally. The Netlify preview is generating fine 🤷‍♂️

I'm also thinking about allowing the functionality to by passing a falsy value and using this as the default, making this a non breaking change. We could follow this up with a breaking release that removes wait and changes the default for interval to be 50ms. I've also wanted to change the default timeout to 1000ms for a while now, so I'd probably bundle that into the breaking change too. I've made it opt in for the initial release. Will follow up with a breaking release which enables it by default, adds a default timeout and removed the deprecated wait utility.
