ESM Loader API has changed in Node 18

[brev]

Node.js 18 has changed the ESM Loader API, as I'm getting a new error with node@18.6.0:

Error [ERR_LOADER_CHAIN_INCOMPLETE]: 
        "node-esm-loader 'resolve'" did not call the next hook in its chain and 
        did not explicitly signal a short circuit. 
        If this is intentional, include `shortCircuit: true` in the hook's return.

}

All my code is still working fine under Node 17.

Experimental ESM Loader Hooks API

Node.js ESM Loader hooks now support multiple custom loaders, and composition is
achieved via "chaining": foo-loader calls bar-loader calls qux-loader
(a custom loader must now signal a short circuit when intentionally not
calling the next). See the ESM docs for details.

Real-world use-cases are laid out for end-users with working examples in the
article Custom ESM loaders: Who, what, when, where, why, how.

Thanks for notifying! Fixed in #5 and published to npm as v0.1.2. I published a new version of node-esm-loader too which uses this new version under the hood.
