CPS-0016: Add new authority to Cardano URI Scheme(s) for dRep delegation

[MadOrkestra]

Just leaving this here, @Crypto2099 and myself will get back to this CPS and the corresponding CIPs in the next months, but feedback is of cause greatly appreciated - the biggest issue with Cardano URI Schemes rn is wallet integration though...

With Cardano governance now in full effect, we should add a new authority to the Cardano URI Schemes to be implemented at some point (sic) by wallets.

I'd propose a //delegate authority which takes in a dRep-Id, so users can scan a QR-Code / click a link, the wallet opens, maybe pulls up the corresponding dRep profile and then lets you delegate to that dRep by just signing the transaction in the wallet.

This would also enable One-Click delegations everywhere with no integrations to be done by websites.

Something to be aware of is the circumstance that you can't delegate to a dRep without being delegated to a stake pool first, which renders this authority useless in case of undelegated wallets, but given we have a lot more wallets not delegated to a dRep, it is still worth the effort to push governance forward.

I'm pretty sure you can actually delegate to a DRep w/o being delegated to a stake pool but probably not many people have actually tested that particular scenario... But in general I am in favor of this. I would support an initial Pull Request adding this as a new "open question" to CPS-0016 and then once a bit more ideation has gone on regarding what all we would need or want from the standard we can create a CIP to address it.

Thats actually a requirement to receive Treasury Withdrawal funds on a StakeAddress. The constitution says that funds received from a TW are not allowed to delegate to a stake pool and must also be delegated to the AlwaysAbstain DRep.
