* Updated supported Node.js versions
Dropped support for 14 and 16 in favor of the current LTS versions 18
and 20.
* Updated Node.js dependencies
Bumped nearly all dependencies to the latest. The exception being
`node-fetch` which made the jump to using ESM which is still causing
folks a lot of grief.
* Shored code coverage back up to 100%
Had some remnants from when this library did sanity checks pre-flight to
the API that required additional tests to cover them, or just adjusting
the argument defaults.
* Removed the "build" badge from the README
Seems there were some gotchas with that badge that makes it kind of a
pain, as it has to be hard coded a certain way. I messed with it and
couldn't get it working, seems like more trouble than it's worth.

* Added .nvmrc file
Pretty self explanatory.
* Bumped version number
Lucky number 7, y'all!
