OnHeaders callback is not accessible.

[singerxt]

Versions of relevant software used 0.15 What happened Response headers are not accessible from the client because the header's callback is not exposed.

What you expected to happen

I should be able to have onHeaders callback provided by grpc_web library.

const response = client.listFiles(req, headers);
response.on('headers', (headers) => {
  console.log(headers);
});

How to reproduce it (as minimally and precisely as possible):

const response = client.listFiles(req, headers);
response.on('headers', (headers) => {
  console.log(headers);
});

will throw an unexpected errors.

I'm more than happy to fix it. However, I'm not sure if this repository is alive.
