Is there any way to mark a model member as required?

[fgimian]

Hey there, thanks heaps for your awesome library!

I was just wondering if it was possible to throw an exception if a particular model field is missing from TOML similar to JsonRequired:

e.g.

using Tomlyn;

var toml = """
full_name = "Mr Happy"
# age = missing!
""";

var person = Toml.ToModel<Person>(toml);

Console.WriteLine($"Person {person.FullName} with age {person.Age}");

public record Person
{
    public string? FullName { get; set; }
    public int? Age { get; set; }
}

This code doesn't throw an exception and simply sets Age to null. I understand that you can specify default values via a parameterless constructor but I was curious if you can set the field as a mandatory / required property and fail when converting using ToModel if the property is missing?

Thanks heaps!
