Summary

• accept RSA public keys encoded as either SubjectPublicKeyInfo or PKCS#1 PEM
• preserve the existing PublicKeyDecodeError API for malformed public keys
• add public-only regression tests for both supported encodings
• release the fix as mauth-core 0.6.1

Why

MAuth registrations can contain PKCS#1 public keys using the
BEGIN RSA PUBLIC KEY envelope.

Verifier::new previously used only from_public_key_pem, which accepts
SubjectPublicKeyInfo keys using the BEGIN PUBLIC KEY envelope. Consequently,
otherwise valid PKCS#1 registrations failed during key loading and surfaced as
KeyUnavailable before signature verification.

Testing
