RNG: AnyRand VRF

[jaybuidl]

Follow up on #1349

anyrand has been audited once, and is running on a freshly deployed drand v2 containing our BLS-on-BN254 scheme by the League of Entropy (Cloudflare, Ethereum Foundation, EPFL, Protocol Labs, Gelato, Zama, ChainSafe Systems etc).

The League of Entropy is a coalition of over twenty independent organizations that power the drand network and contribute to publicly-verifiable randomness generation.
