Add PaymentResponse wrapper

This is an experimental wrapper around the send_payment shortcut calls.
The goal is to provide a simple interface to check if the payment was
successful.

 ## Installation
 
+Note: there is still an GRPC/protobuf [issue with Ruby 2.7](https://github.com/protocolbuffers/protobuf/issues/7070). 
+So lnrpc requires Ruby < 2.7.
+
 Add this line to your application's Gemfile:
 
 ```ruby
-gem 'lnrpc', '~> 0.6.1'
+gem 'lnrpc', '~> 0.10.0'
 ```
 lnrpc follows the lnd versioning, thus it is recommended to specify the exact version you need for your lnd node as dependency (see [#Versioning](#Versioning)).

 ### Client wrapper
 
+NOTE: v10.0 has breaking changes!
+
 An optional client wrapper ([Lnrpc::Client](https://github.com/bumi/lnrpc/blob/master/lib/lnrpc/client.rb)) makes
 initializing the gRPC client easier and removes the need for some boilerplate code for calling RPC methods.
 
 #### Example
 ```ruby
 lnd = Lnrpc::Client.new({credentials_path: '/path/to.cert.cls', macaroon_path: '/path/to/admin.macaroon'})
-lnd.get_info
