1GB inputs to usdzip generate 2GB usdz file

[jcowles]

Description of Issue

Subject says it all.

Steps to Reproduce

1. Localize files into a directory
2. cd into the directory
3. run "usdzip Volund.usdz ."

First problem, usdzip attempts to zip the temp usdz file:
usdzip Volund.usdz .
Skipping empty file '.\Volund.vhdmao'.

When complete, the generated usdz file is 2GB, but the source files are 1GB total.
Let me know if you want my actual source files.

System Information (OS, Hardware)

Windows 10

Package Versions

USD 18.11

Build Flags

--openimageio --alembic

This was due to duplicate archiving, which is fixed in our dev tree, and I believe was the result of commit 9bfcf49 . Jeremy I'd like to note that your give usdzip command-line won't produce a legit usdz archive... when not using the "--asset" or "--arkitAsset" flags, you must provide the root/default usd file as the *first *file following the usdz file. I successfully made an archive like so: usdzip Volund.usdz VolundModel.usda * We should definitely document this better.
