A local run failed until I added this line to my .npmrc

@open-cmsis-pack:registry=https://npm.pkg.github.com

Would you expect this to be needed? If so, we should update DEVELOPMENT.MD.

Important: you need to clean caches after a successful run with workarounds/fixes.

Also, I saw trouble running the tool download locally on Windows. Looked like what I saw before which made me move to the other unzipper for Windows. But went away on subsequent runs. Scary but looks like no real problem.

True, this needs to be added.
