Function verify_signature_share 

pub fn verify_signature_share<C: Ciphersuite>(
    identifier: Identifier<C>,
    verifying_share: &VerifyingShare<C>,
    signature_share: &SignatureShare<C>,
    signing_package: &SigningPackage<C>,
    verifying_key: &VerifyingKey<C>,
) -> Result<(), Error<C>>

Verify a signature share for the given participant identifier, verifying_share and signature_share; with the signing_package for which the signature share was produced and with the group’s verifying_key.

This is not required for regular FROST usage but might be useful in certain situations where it is desired to verify each individual signature share before aggregating the signature.
