node 12 support?

[achingbrain]

v3 of this module refactored to use esm modules and set the engines field to require node >= 14, yet this module is published transpiled to common js so does run on node 12 at least.

If a user has engine-strict = true or is running yarn, it'll fail to install on node 12 even though it will run.

Can the engines field be relaxed? Node 12 is active LTS for another few months and maintenance LTS until spring 2022 so dropping support seems premature.

BTW, this module is not transpiled, but uses an an ESM-Wrapper:
