Hash to Grpc object converter

This is a simple library to convert a hash to grpc object

eg.

Sample Proto file (.proto) :

   syntax = "proto3";

    package cpqgrpc.product.v1;

    message ProductRequest {
      uint64 id = 2;
      string name = 3;
      repeated string categories = 4;
   }

  message ProductResp {
      uint64 id = 2;
      string name = 3;
      repeated string categories = 4;
   }

  service Product {
    rpc GetProduct (ProductRequest) returns (ProductResp);
  }


  Sample generated service (.rb):
    require 'google/protobuf'

    require 'cpqgrpc/custom_types_pb'
    Google::Protobuf::DescriptorPool.generated_pool.build do
       add_message "cpqgrpc.product.v1.ProductRequest" do
         optional :id, :uint64, 2
         optional :name, :string, 3
         repeated :categories, :string, 4
       end
    end

    module Cpqgrpc
       module Product
           module V1
               ProductRequest =    Google::Protobuf::DescriptorPool.generated_pool.lookup("cpqgrpc.product.v1.ProductRequest").msgclass
               ProductResp = Google::Protobuf::DescriptorPool.generated_pool.lookup("cpqgrpc.product.v1.ProductResp").msgclass
           end
       end
    end

Above are the sample generated protos

1. To convert hash { id: 1, name: 'Macbook' } to Grpc object Cpqgrpc::Product::V1::ProductRequest use below

   GrpcDataTransformers.hash_to_grpc_object( { id: 1, name: 'Macbook', categories: ['hardware', 'laptop'] })
