Hello! When running unused, unused --help, and unused doctor, I get the following error:

With fish:

fish: 'unused' terminated by signal SIGSEGV (Address boundary error)

With zsh:

zsh: segmentation fault  unused

I have unused version 0.2.0 installed via Homebrew (unused-code/formulae) on macOS Big Sur 11.2.3 with an M1 Macbook. ctags were successfully generated with Universal Ctags. Maybe it's something weird with the M1 architecture?

If there's anything I can do to help debug, let me know!
