Multiple CVEs and no releases since 2004.

No objection from me 👍. Not something I've ever used myself, just noticed it pop up on Debian's security list.

I understand the trouble that a package with no upstream maintainer can pose, and I do use bchunk from time to time when I need to convert old mixed-mode CD image backups for use on macOS. I can always fall back to building from source myself in future, but I did want to just let you know that there is still at least one user of bchunk from Homebrew out here on the internet who appreciated this formula existing.

@csnover I'm happy to re-add it if you can convince upstream to cut a new release with the CVE fixes included. There is still contact information on http://he.fi/bchunk/ so even though there hasn't been any activity in 10 years, someone might respond. In the meantime you can put the formula in your own tap.
