Added support for complex types in config

[helto4real]

Proposed change

NetDaemon now supports usage of complex types in configurations.

Example:

complex_app:
    class: AppComplexContif
    a_string: hello world
    an_int: 10
    a_bool: true
    a_string_list:
    - this
    - is
    - cool!
    devices:
    - name: tv
        commands:
        - name: command1
            data: some code
        - name: command2
            data: some code2";

public class AppComplexConfig : NetDaemonApp
{
    public string? AString { get; set; }
    public int? AnInt { get; set; }
    public bool? ABool { get; set; }
    public IEnumerable<string>? AStringList { get; set; }
    public IEnumerable<Device>? Devices { get; set; }
    public override Task InitializeAsync()
    {
        // Do nothing

        return Task.CompletedTask;
    }
}

public class Device
{
    public string? name { get; set; }
    public IEnumerable<Command>? commands { get; set; }
}
public class Command
{
    public string? name { get; set; }
    public string? data { get; set; }
}
