VRF validation

[sandtreader]

Validate the VRF calculation in the block header, based on the slot number, the quoted VRF key hash and the SPDD you can look up the SPO to find the proportion of stake. There should be support for this in Pallas real soon now - check with Pavo.

On either success or failure it should generate a ValidationResult message (TBD) on "cardano.validation.vrf".

• We already have epoch data
• missing KES data?

Acceptance Criteria

• Tests exist that show failure on an invalid block
• Tests exist that show validation on every block on mainnet
• Log an error on every block that fails
