feat(serialization): add serialization based on specific header value

[harry-detsis]

This MR adds a new serialization strategy that allows the serialization/deserialization of messages based on the presence and value of a specific header. This is to allow consumers to consume messages that do not have their message types set to the name of the assembly of the serialization/deserialization target.

To use this functionality, simply register a producer or consumer as follows:

new RabbitMqServiceBuilder<MyConusmer>()
    .WithRabbitMqConfig(rabbitMqConsumerConfiguration)
    .WithHeaderTypedMessages(new HeaderTypeSerializationConfiguration
    {
        TypeHeader = "x-my-header",
        TypeMappings = new Dictionary<string, Type>
        {
            {"my.type", typeof(MyType)}
        }
    })
    .Build(_serviceCollection)
    .Add(_serviceCollection, typeof(MyConusmer));
