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
