Add macOS 13 Ventura to the script

Is it possible to add the Ventura beta version to the script?

Hi, thanks for the enhancement request. Adding more macOS versions like Big Sur and Monterey is definitely possible, but I have no plans for any major updates to the script. To recap issue #547 regarding Big Sur and Monterey, the script needs to use 7zip to extract from the xar archive and extract from the resulting Payload~, then use those extracted files to create a bootable installer almost (or exactly) the same way the script does now. Additionally, Monterey seems to require the VirtualBox parameter TSCMode set to RealTSCOffset, and Ventura might require some parameter tweaks regarding AVX2.

Currently I have no plans to update the script, but I'll certainly look into any pull requests implementing the 7zip process or fixes to any of the other bugs and enhancement requests.
