Motivation: Binary metadata values are encoded as base64 strings. The gRPC spec doesn't require that the values are padded. Currently gRPC Swift requires values to be padded otherwise decoding will fail. Modifications: - Allow padding characters to be omitted when decoding base64 Result: Can decode unpadded binary metadata values
