docs: Returns protocol buffer utility descriptor.
  Takes a loaded grpc / protocol buffer object and returns a friendlier descriptor object
  @param  {Object} input loaded proto object
  @return {Object} the utility descriptor
  @example
  const gi = require('grpc-inspect')
  const grpc = require('grpc')
  const pbpath = path.resolve(__dirname, './route_guide.proto')
  const proto = grpc.load(pbpath)
  const d = gi(proto)
  console.dir(d)
