To set request header

[n04ln]

Currently, request is set only Content-Type header. So, I suggest a solution to set other header. (This solution is inspired by gRPC)

1. define CallOptions class (like following code) in https://github.com/apptreesoftware/twirp_dart_core

   class CallOptions {
   Map<String, String> headers;
   CallOptions() {
       headers = new Map<String, String>();
   }
   void setHeader(String key, String value) {
       headers[key] = value;
   }
   }

2. call rpc method with CallOptions

   // define by auto-generated file
   Future<UserProfile>getMyProfile(Empty empty, {CallOptions opts}) async {
   ...
   if (opts != null) {
       opts.headers.forEach((String k, String v) {
           request.headers[k] = v;
       });
   }
   ...
   }

   // call
   var opts = new CallOptions();
   opts.setHeader("Authorization", "Bearer ${token}");
   var res = service.getMyProfile(new Empty(), opts: opts);

I implemented in https://github.com/NoahOrberg/protoc-gen-twirp_dart/tree/n/hotfix/inner-class. (but, CallOptions definition is included auto-generated file, and don't mention this branch name..)

@NoahOrberg This is already possible. The Default<ServiceName> method takes a Requestor. It is not a required param but if you pass it it allows you to customize the request. A Requestor allows you to supply number of Middleware. The Middleware gives you hooks for modifying the request before it goes out.
