Factory method to create an SolanaSigner instance from key bytes.
Implementation
factory SolanaSigner.fromKeyBytes(List<int> keyBytes) {
// Create an EDDSA private key from the key bytes using the ED25519 curve.
final signingKey = EDDSAPrivateKey(
SolanaSignerConst.ed25519Generator, keyBytes, () => SHA512());
return SolanaSigner._(signingKey);
