AddSorted method for Collections

[Panda-Sharp]

Hi all,

OservableGroup and ObservableGroupCollection are really nice, but there is no easy way to keep them ordered, I implemented some simple AddSorted extensions methods to add the new item in the proper position and keep them ordered, they're not fully optimized yet but I think it's a good base, you can find them here:

https://github.com/Panda-Sharp/Yugen.Toolkit/blob/develop/Yugen.Toolkit.Uwp/Extensions/ObservableGroupedCollectionExtensions.cs

https://github.com/Panda-Sharp/Yugen.Toolkit/blob/develop/Yugen.Toolkit.Uwp/Extensions/ObservableGroupExtensions.cs

I implemented the same extensions methods also for ObservableCollection, these ones works also with a comparer, here

https://github.com/Panda-Sharp/Yugen.Toolkit/blob/develop/Yugen.Toolkit.Standard/Extensions/ObservableCollectionExtensions.cs

P.s.
The same could be done also for Lists

Cheers

Thanks, @Panda-Sharp for the proposal and showcasing your work. @Sergio0694 what do you think about AddSorted extensions running in the ObservableGroup?
