[dipanshuhappy]

What feature should we add?

Implementing a function in the ens modules, called get_avatar which implements the ENIPS (https://docs.ens.domains/ensip/12/)

http(s): - URI Scheme for HTTP(S) URLs. Libraries will most likely return the result directly.
ipfs: - URI scheme for IPFS hashes. Libraries may decide to fetch the result from a public gateway for you.
data: - URI Scheme for data URIs. Libraries will most likely return the result directly.
eip155: - The URI scheme for EIP-155 identifiers for linking to NFTs on Ethereum based chains. A little complicated to resolve manually, most libraries should resolve this for you and return the underlying resource.
