* crypto: Use curve25519-voi This switches the ed25519, sr25519 and merlin provider to curve25519-voi and additionally adopts ZIP-215 semantics for ed25519 verification. * crypto: Implement batch verification interface for ed25519 and sr25519 This commit adds the batch verification interface, but does not enable it for anything. * types: Use batch verification for verifying commits signatures
