require fallback

[Eomm]

Adding the require fallback to support yarn in PnP mode.

Added workflows to test it.
Note I had to add a new script in package.json because the mjs files do not work with yarn (it doesn't support esm yet)

There is a repetitive warnings in the output

test/thread-management.test.js 2> (node:3755) [MODULE_NOT_FOUND] Error: debug tried to access supports-color (a peer dependency) but it isn't provided by its ancestors; this makes the require call ambiguous and unsound.

caused by some dependencies that have not added the module into their package json.
Not sure it is worth some investigation

Reference pinojs/pino#1113

Could you add some doc about this in the README?
