Function schnorrkel::verify_batch_rng

pub fn verify_batch_rng<T, I, R>(
    transcripts: I, 
    signatures: &[Signature], 
    public_keys: &[PublicKey], 
    deduplicate_public_keys: bool, 
    rng: R
) -> SignatureResult<()> where
    T: SigningTranscript,
    I: IntoIterator<Item = T>,
    R: RngCore + CryptoRng, 

Verify a batch of signatures on messages with their respective public_keys.

Inputs and return agree with verify_batch except the user supplies their own random number generator.
