Version 2.5.0

The most important thing for most users is that PHP 8.4 deprecation warnings will no longer be emitted by this library.

However, we did introduce a deprecation of our own: The SchnorrSignature class is now deprecated and has been replaced
by an identical class called SchnorrSigner. Code that used the old name will continue to function until the next
major version release.

What's New

SchnorrSigner - signWithKey(), verifyWithKey()

The Schnorr implementation we adopted in v2.4.0 didn't blend in seamlessly with the rest of the PHPECC user experience,
so now there are two new methods, signWithKey() and verifyWithKey(), that expect key objects rather than hexadecimal
encoded strings.

$schnorr = new \Mdanter\Ecc\Crypto\Signature\SchnorrSigner();

$signature = $schnorr->signWithKey($privateKey, $message);

var_dump(get_class($signature));
// string(38) "Mdanter\Ecc\Crypto\Signature\Signature"

$valid = $schnorr->verifyWithKey($publicKey, $message);
if (!$valid) {
    die("invalid signature");
}
