feat(smart-contracts): advanced token URI hook

[julien51]

Description

For FarCon, our friends at Icreabreaker.xyz are using their own backend fo the metadata, but they need to have the owner's address in the URL, rather than just the token id.
We're adding a custom onTokenURI hook that provides an advanced setup.

Shouldn't we use import?
