Custom components aren't being registered by the extension

[jinwood]

Expected behavior

After creating a custom component, MJML extension should register it and not show an error in templates.

Actual behavior

MJML is not picking up the custom component, and as a result shows errors in the template:

Not sure if this is relevant, but the extension seems to hang with this popup:

Steps to reproduce the problem

See repo here.

1. Clone, npm i
2. npm run build
3. Observe extension behaviour in snippets/index.html

In my case extensions was in ES syntax (.mjs), and Node JS somehow couldn't import them from commonjs code, seems like i need to add some preprocessing to convert them to cjs, to make extension work
