Echo JS 0.11.0

The size of this library could be problematic... I'm unsure of the dependency on @babel/core as this should not be relying on that level of translation for a shared component library.

I'm not the one who down-voted, all the same, still would be cautious in its' use.  Would be better to publish the mjs modules directly instead of translating, or only transforming those specific features needed for this module in its' output.

It is also missing a LICENSE file in the project, even though MIT is marked in the package.json.
