Add a KotlinJS JAR as a NPM dependency

[darren-bell-nanthealth]

The Kotlin Multiplatform Plugin generates JsJars. Unfortunately, there doesn't seem to be a straight forward way to reference that as an NPM dependency in the plugin. Something like:
kotlinFrontend { sourceMaps = true npm { dependency(":common") } }
There is another plugin https://github.com/svok/kotlin-jar2npm-plugin that looks like it should work. However, it seems to clash with the Multiplatform plugin.
Is there an alternative? Is there a way to reference the output? Something like:
kotlinFrontend { sourceMaps = true npm { dependency("file:../common/build/classes/js/main") }
I'm a bit stuck with this at the moment, any help would be gratefully recieved.

Thanks
