Mmm fairly sure we don't call SelectionChanged to avoid performance issues in big folders

I seem to recall that we did this in the past but reverted the change because of performance issues.

Perhaps a happy medium would be to wait a couple seconds between every update.

Updated, so now SelectionChanged is called only when selected items have changed.

If we were to do this, we could just stop unsubscribing the selection changed event in the PointerPressed event handler.. but the performance issue would persist. We could check again how bad it gets though.

@IgorKordiukiewicz is this ready for review?

I implemented the changes, but haven't tested the performance, so I don't know tbh, maybe it is?

@gave92 should we move forward with this, if not, what do you want to do here?

@IgorKordiukiewicz thank you!
