Export "holders" including delegated tokens

[scottrepreneur]

Is your feature request related to a problem? Please describe.
I'm frustrated when I want to use Purple tokens in other token-gating tools but can only rely on immediate holders. I'd prefer to use delegated addresses.

Describe the solution you'd like
Provide an option to export the current set of delegated addresses. Usually, when we get token holders this is the actual set we want. Etherscan and others provide a naive balance of tokens.

• Probably relies on Index and show my DAOs when I'm only delegated tokens #464

Describe alternatives you've considered
Could be possible once the subgraph makes this available, but still hard and otherwise not available.
