Feathers ESM Support

[gorango]

The current setup requires us to clone the src/ of each new version of feathers-pinia to the nuxt app dir.

My rough understanding is that this is due to CommonJS/ESM incompatibilities with the @feathersjs/* packages and the nuxt build system?

I am opening this in order to:

• get a better understanding of the issue and see what can be done to improve DX
• track the state of ESM in feathers
