XCode Instruments 16 breaks Deep Copy format import

[akumansley]

Here's a sample Deep Copy from Instruments 16, which seems to have slightly different spacing:

Weight	Self Weight	Symbol Names
2.18 s  100.0%	0 s	 node (98674)
1.98 s  90.8%	0 s	  start
1.98 s   0.0%	0 s	   node::Start(int, char**)
1.98 s   0.0%	0 s	    node::LoadSnapshotDataAndRun(node::SnapshotData const**, node::InitializationResult const*)
1.98 s   0.0%	0 s	     node::NodeMainInstance::Run()

Hi! Thanks for the heads up. I'd accept a PR to resolve this while still maintaining functionality for past versions of Instruemnts. The relevant file to change is importFromInstrumentsDeepCopy

Hi there, unfortunately, I also have a broken .trace from use of XCode 16. When do you think it can go productive with this fix?

@akumansley @robert3005 This is now merged and live on https://www.speedscope.app/

@MAUIoxo Unfortunately, I think your issue is slightly different an unlikely to be resolved. Instruments' file format has evolved significantly since I wrote the support for Instruments import and I never got around to doing the added reverse engineering work to figure out what's going on. See #196. It's possible using "deep copy" as a workaround will still allow you to accomplish what you need to though.
