EnumListHandler should skip lists that have an ExistsIn attribute

[fsateler]

This way one could have a form using an enum but limiting the usable values (useful for when one is creating multiple distinct forms for the same general operation), or replacing the enum text values.

public override bool CanHandle() => 
    GetUnderlyingType(FieldGenerator).IsEnum && !HasExistInAttibute();

private bool HasExistInAttibute() => 
    FieldGenerator.Metadata.AdditionalValues.ContainsKey(ExistsInAttribute.ExistsKey)
    && FieldGenerator.Metadata.AdditionalValues[ExistsInAttribute.ExistsKey] as bool? == true;

Very reasonable. Feel free to raise a PR :)
