Require Node 16+ while building/testing on Node 20 (#596)

* Use canonical encoding/readFile command to take advantage of fast path in Node 20

Fast path doesn't appear to check encoding options case insensitive, 'utf8' seems more canonical.

* Migrate build to Node 20

Node 16 is nearly EOL, and Node 20 is nearly LTS, so let's go straight there. This remove use of a deprecated npm flag, replacing with alternative compatible with npm 7/NodeJS 16 onwards (2021+, Node 16 recently went EOL in Sep 2023). The package-lock is also now only compatible with Node 16/npm 7 onwards.

Since this is technically a breaking change in npm/node compatibility, bumps the major version and updates the documentation as such.
