Context

We want to augment spo-stake-distribution with extra information (this is #911), which is what we do in this PR. However, we will be able to simplify this PR when using IntersectMBO/cardano-ledger#4735.

But @gitmachtl tagged this as important to have before the Christmas vacation, so here is this PR with a more complex implementation until we integrate the ledger.

Fixes #911

An earlier version of this PR (based on cardano-cli 10.1.0.0 tag) is still available here: https://github.com/IntersectMBO/cardano-cli/commits/smelc/10.0.01-hoops-augment-spo-stake-distribution/

[smelc]

@gitmachtl> can you test this PR? (like before, you need https://github.com/IntersectMBO/cardano-api/commits/smelc/legacy-additional-exports/, there is an SRP in this PR).

---

Note that I haven't forgotten about the renaming of the command (for example to spo-votepower-distribution) but didn't want to mix the renaming with this PR.

Also note that we'll need to wait for @Jimbo4350 to approve this temporary solution until we can update the ledger.

[smelc]

@gitmachtl> did you have time to try this one?

[gitmachtl]

@smelc hey, not yet. will do in a bit. thanks for the reminder! helped to sort out some daedalus issues yesterday...

[gitmachtl]

@smelc this is looking pretty good!

I compared them and they are identical, just koios returns the CIP129 drep format. But its the same Hash and same lovelaces. This is looking ok!

I also checked about DRep-Script delegations on Mainnet, currently two pools have there rewards account delegated to a DRep-Script:

./cardano-cli conway query spo-stake-distribution --all-spos | jq -r '[.[] | select((.[2] // "") | contains("script"))] | sort_by(.[0])'

I checked both pools via adastat.net and the delegation is correct too. 🎉

Thats awesome 😄
