Typo in eddilithium3 package: References to "eddilithium4"

[y12studio]

There are multiple instances where the eddilithium3 package incorrectly references "eddilithium4" in error messages. This appears to be a typo that needs to be corrected.

$ curl -s https://raw.githubusercontent.com/cloudflare/circl/v1.3.9/sign/eddilithium3/eddilithium.go | grep -A2 -B2 eddilithium4

func (pk *PublicKey) UnmarshalBinary(data []byte) error {
	if len(data) != PublicKeySize {
		return errors.New("packed public key must be of eddilithium4.PublicKeySize bytes")
	}
	var buf [PublicKeySize]byte
--
func (sk *PrivateKey) UnmarshalBinary(data []byte) error {
	if len(data) != PrivateKeySize {
		return errors.New("packed private key must be of eddilithium4.PrivateKeySize bytes")
	}
	var buf [PrivateKeySize]byte
--

	if opts.HashFunc() != crypto.Hash(0) {
		return nil, errors.New("eddilithium4: cannot sign hashed message")
	}
