FIP (DRAFT IDEA): Casting from Smart Contracts

[parseb]

Motivation:
Make it possible for a contract to cast.
DAO, or composed agent, or as programmable assets; "social media" accounts are needed.

Solution 1 (strict):
Delegate FID Nonce with Content Hash
How: Allow a contract that controls an FID to associate a specific nonce to a cast content hash.
So that:
Any arbitrary signer can trigger the next cast on behalf of an FID provided that the content hash matches the fid specified one.

Solution 2 (generalized):
Delegate an FID Nonce to another FID.
Same effect, but inverse roles: content is arbitrary, signer is specific.
Uses: Monetization. Social apps.

Solution 3 (unlikely):
Add support for EIP1271 signature verification.

Requirements:
Add and enforce mapping between FID nonce and content hash or beneficiary.

TODO:
Understand more how contracts interact with hub.
