Implement Greeter

Create Greeter and implement the sayGreet method:

./server.js

class Greeter {
  constructor() {
    this.count = 0
  }
 
  async sayGreet(call) {
    const { name } = call.request
    this.count++
    return {
      message: `hello ${name || "world"} by Greeter`,
      count: this.count,
    }
  }
}
