Incorrect default modifier order

[nicklockwood]

This reads weirdly to me, and seems not to match Apple conventions, e.g. https://developer.apple.com/documentation/avfoundation/avplayeritem/init(asset:)-1nme9

convenience nonisolated init() { ... }

Any objection to me changing the default order to this @calda ?

nonisolated convenience init() { ... }

Good idea makes sense to me 👍🏻
