Tried this just now, and got this, trying to extract the macOS 13.1 x86_64h cache:

Looks like only two changes are required to get this added to the BN plugin manager. The first is to add a requirements.txt -- while ktool and DyldExtractor are versioned, capstone is still a requirement of DyldExtractor so it would be nice to expose that.

Or, better yet, replace the disassembler with BN's own disassembly to remove the dependency entirely. That also means there's no need to hack around the lack of PAC instructions as BN can disassemble those just fine.

The other step is to make a release, then we can add the plugin directly to the plugin manager which would be really handy!

I'm not sure whether it's the exact python version or the fact that I'm using the BN shipped Python versus homebrew / ports but I'm unable to use the plugin as-is on MacOS without this change. I don't know how much this versioned DyldExtractor has differed, happy to test/submit upstream in the parent repo if you prefer.
