type coverage testing

[naseemkullah]

As to avoid too many instances of any slipping in, we may want to include https://www.npmjs.com/package/type-coverage in our workflow. Thoughts? After adding it as a dev dependency, a script of the sort:

    "typecov": "type-coverage --detail --at-least=99"

would ensure at least 99% of types are not any.

I'm not sure, we generally only use any when the instrumentation patching is too complex to correctly type it. Adding a percentage may require us to decrease it if we are forced to add any for instrumentation :/

Is there a way to drop it for just instrumentation packages? I could see it being valuable in the core packages.

@naseemkullah would that satisfy you? If so, would you like to tackle this?

Sounds good!
