Replace old HUI dependency with Hero UI peer

Having projects with HUI and EDH Widgets alongside causes all sorts of problems where two incompatible versions of react get loaded alongside each other. After a review of EDH widgets, it's clear that the only thing HUI is using is importing three SCSS files as a source for colour and other variables.

Since these files also exist in the latest HUI, its safe to pin to that.

I've also moved the HUI, React, and ReactDOM dependencies to peer dependencies. This still allows us to specify version preferences, but won't install parallel incompatible versions in apps that use this alongside their own React installs.
