Extend another message

One proto now support extend another message (merge) by specifying extend in the message options.

Please see [user.proto](./example/proto/user.proto) for example

```proto
// import oneproto.proto. This will not effect the tool nor output, this is to make the IDE happy.
// You might want to include "go list --json github.com/joesonw/oneproto | jq -r '.Dir'" 

import "oneproto.proto";
