Part 7: Getting to (non-beta) ARKit compliance for my scripted usda outputs is going to be uglier than I had hoped since usdc files are required.
Figured that out by coaxing the Apple provided usdARKitChecker to pass through a little more info from usdchecker util, and then smooshed the files together using usdcat. Unclear on how to do this all in Swift down the line, but works for now!
