Support Snapshot delegation

[shalzz]

What is the new protocol to be added? Is it a direct Compound/Uniswap fork or something else?> Snapshot now supports delegation via the Gnosis delegate registry found here: https://github.com/gnosis/delegate-registry/blob/main/contracts/DelegateRegistry.sol

This is integrated directly by the snapshot team, allowing anyone to delegate their tokens across snapshot spaces or limit to just one space via: https://snapshot.org/#/delegate

The snapshot team has their own fork and subgraph available here: https://github.com/snapshot-labs/snapshot-subgraph and running at: https://thegraph.com/explorer/subgraph/snapshot-labs/snapshot?selected=playground

Provide governance details (all may not apply if not direct Compound Governance fork) This with allow any protocol listed on snapshot.org to be supported by the sybil-interface and can potentially share the metadata of a protocol used by the snapshot interface to setup a space.

Additional context This can potentially have the same goals and effects of #70
