Add a generic add/get function [Suggestion]

[DVDPT]

It would be very nice to have a generic function to get and add info, that would enable to do generic treatment (e.g INPC events) also in a generic way.

An usage example: Current

public string MySetting
        {
            get => CrossSettings.Current.GetValueOrDefault(nameof(MySetting), "");
            set
            {
                CrossSettings.Current.AddOrUpdateValue(nameof(MySetting), value);
                RaisePropertyChanged(nameof(MySetting)); // this line repeated on every setting
            }
        }

Possible public interface

public string MySetting
{
    get { return GetSetting(nameof(MySetting), ""); }
    set { SetSetting(nameof(MySetting), value); }
}

public void SetSetting<T>(string name, T @default)
{
    if(CrossSettings.Current.AddOrUpdateValue(name, @default))
         RaisePropertyChanged(name);

}

This was already removed as it can be abused since it doesn't support all data types.

An InvalidArgumentException would put a stop on possible abuses xD
