 -- | Obtain stake snapshot information for a pool, plus information about the total active stake.
 -- This information can be used for leader slot calculation, for example, and has been requested by SPOs.
 -- Obtaining the information directly is significantly more time and memory efficient than using a full ledger state dump.
