Refactor channel class names to use Client prefix.

Instead of UaTcpSessionChannel, use ClientSessionChannel. See Readme for details.

        // create a 'ClientSessionChannel', a client-side channel that opens a 'session' with the server.
        var channel = new ClientSessionChannel(
            clientDescription,
            null, // no x509 certificates
            new AnonymousIdentity(), // no user identity
            "opc.tcp://opcua.rocks:4840", // the public endpoint of a server at opcua.rocks.
            SecurityPolicyUris.None); // no encryption

Bug fixes: Check expired certificate. Message chunking.

v3.1.1

Support GetValueOrDefault<> of custom type.

v3.1.0

Support for creating a Type Library of custom Structures

In v3.0, we ask that you mark the assembly containing your custom structures with TypeLibrary() attribute.
The Encoder/Decoder will discover these custom structures and be able to read and write these structures with the server.

using System;
using Workstation.ServiceModel.Ua;

[assembly: TypeLibrary()]
namespace CustomTypeLibrary
{
    [DataTypeId("nsu=http://www.unifiedautomation.com/DemoServer/;i=3002")]
    [BinaryEncodingId("nsu=http://www.unifiedautomation.com/DemoServer/;i=5054")]
    public class CustomVector : Structure
    {
        public double X { get; set; }
        public double Y { get; set; }
        public double Z { get; set; }
        public override void Encode(IEncoder encoder)
        {
            encoder.WriteDouble("X", X);
            encoder.WriteDouble("Y", Y);
            encoder.WriteDouble("Z", Z);
        }
        public override void Decode(IDecoder decoder)
        {
            X = decoder.ReadDouble("X");
            Y = decoder.ReadDouble("Y");
            Z = decoder.ReadDouble("Z");
        }
    }
}

Nullable Reference Types

Adopt nullable reference types (NRT) in preparation for .NET 5.

Thank you, @quinmars

Ignore UTF8 decoder errors. Send nonce, local cert with CreateSession always.
