Function sign_grind_r

pub fn sign_grind_r(
    msg: impl Into<Message>,
    sk: &SecretKey,
    bytes_to_grind: usize,
) -> Signature

Constructs a signature for msg using the secret key sk, RFC6979 nonce and “grinds” the nonce by passing extra entropy if necessary to produce a signature that is less than 71 - bytes_to_grind bytes. The number of signing operation performed by this function is exponential in the number of bytes grinded. Requires a signing capable context.
