Usually if you do export to project serveral times, ILSpy saves types with accompanying attributes in different order

It'd be very nice to happen if the order of attributes would be sorted in some order and will be constant from export to export

Overall benefit of this feature would be to have shorter time to find the diff between multiple exports thus making end-users even more happy :)
