is_valid_p256_signature

This function assumes the s component of the signature to be positive for efficiency reasons. It is not recommended to use it other than for validating account signatures over transaction hashes since otherwise it’s not protected against signature malleability. See https://github.com/OpenZeppelin/cairo-contracts/issues/889.
