`import-in-the-middle` has some ESM interop issues. From [here](open-telemetry/opentelemetry-js#4546 (comment)): > Specifically, namespace imports are required by the ESM spec to be objects. IITM's top-level export is not an object, but a callable function This causes [issues](open-telemetry/opentelemetry-js#4717) with some bundlers. Obviously bundled imports will not go through `import-in-the-middle` but using it should not inhibit bundlers as iitm can still hook build-in modules. This adds a `Hook` named export and changes one cjs and esm test to use that new export.
