`BytesExtension` class should be public

[rognierbenoit]

Hi, in 2.0.1 version, shouldn't BytesExtension class in Netezos.Utils.Extension be public ? otherwise the usage example in README.md bytes.Concat(signature) or Netezos.BytesExtension.Concat(bytes,signature) does not seem to work.

I get the following message: 'BytesExtension' is inaccessible due to its protection level

Hi! There is an overload Rpc.Inject.Operation.PostAsync(IEnumerable<bytes> data) which takes IEnumerable<bytes>, so you can use the native System.Linq to concat bytes.

Here is a complete code of the example in README:

using System.Linq;
using System.Threading.Tasks;

using Netezos.Forging;
using Netezos.Forging.Models;
using Netezos.Keys;
using Netezos.Rpc;

namespace NetezosExample
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // or use existing one
            var key = Key.FromBase58("edsk4ZkGeBwDyFVjZLL2neV5FUeWNN4NJntFNWmWyEBNbRwa2u3jh1");

            // use this address to receive some tez
            var address = key.PubKey.Address; // tz1SauKgPRsTSuQRWzJA262QR8cKdw1d9pyK

            using (var rpc = new TezosRpc("https://delphinet-tezos.giganode.io/"))
            {
                // get a head block
                var head = await rpc.Blocks.Head.Hash.GetAsync<string>();

                // get account's counter
                var counter = await rpc.Blocks.Head.Context.Contracts[address].Counter.GetAsync<int>();

                var content = new ManagerOperationContent[]
                {
                    new RevealContent
                    {
                        Source = address,
                        Counter = ++counter,
                        PublicKey = key.PubKey.GetBase58(),
                        GasLimit = 1500,
                        Fee = 1000 // 0.001 tez
                    },
                    new TransactionContent
                    {
                        Source = address,
                        Counter = ++counter,
                        Amount = 1000000, // 1 tez
                        Destination = "tz1KhnTgwoRRALBX6vRHRnydDGSBFsWtcJxc",
                        GasLimit = 1500,
                        Fee = 1000 // 0.001 tez
                    }
                };

                var bytes = await new LocalForge().ForgeOperationGroupAsync(head, content);

                // sign the operation bytes
                byte[] signature = key.SignOperation(bytes);

                // inject the operation and get its id (operation hash)
                var result = await rpc.Inject.Operation.PostAsync(bytes.Concat(signature));
            }
        }
    }
}

Thank you Groxan for the response! it works fine.
