CAIP10 support for Arweave Wallets

# Arweave compatibility with CAIP10

This is a low priority enhancement that should eventually be applied to the Ceramic Libraries.

I've created an Auth Provider here: https://gist.github.com/rsoury/72e0a79210ea156b2110fd3c19b2bb58
The intent is for compatibility with https://github.com/ceramicnetwork/js-ceramic/tree/develop/packages/blockchain-utils-linking

While desiring and attempting to develop the support, I soon realised that https://github.com/ceramicnetwork/js-ceramic/blob/develop/packages/blockchain-utils-validation is a dependency for the Core Ceramic Node meaning that integration would require a fork of the entire node.
Correct me if I'm wrong on the above statement.

I'm unsure at the moment if running a forked Node is advised.

In the meantime, I'll use `authId` & `authSecret` method for Arweave-based DID authentication.
