> This should check/set the buffer's endianness. This came up while debugging an issue in Flight; PutResult#fromProtocol asks Protobuf for the byte buffers that underlie a ByteString, but if the implementation is LiteralByteString, Protobuf has no buffers. So it wraps the underlying byte[], and of course the default endianness is BIG_ENDIAN.
