Node 18 and eslint 8 fixes

[chappjc]

This resolves a build error I encountered with Node 18, but is apparently related to the version of eslint-config-standard we were using that was not quite compatible with eslint 8.

standard/eslint-config-standard#202
standard/eslint-config-standard#209

This updates the npm deps to resolves that.

This also gets CI running on Node.js 16 and 18, which are the LTS and "Current" version supported: https://nodejs.org/en/download/
