We added `yanked = true` to the advisory, however it doesn't seem to be
having the intended effect (the query for unmaintained crates is
probably failing to exclude the yanked advisories)
This is another workaround which makes the `unaffected` requirement
match all versions. Hopefully this means that `spin` will stop being
reported as unmaintained.
As proposed in #240 and tracked in #414, this PR translates all
advisories into the new "V3" advisory format, which is based on Markdown
with leading TOML front matter.
This format makes it easier to see rendered Markdown syntax
descriptions, whether rendered by an IDE or GitHub. This should help
with both crafting advisories initially as well as review, and ideally
encourages more lengthy descriptions.
Support for this format shipped in `cargo-audit` v0.12.0 on
May 6th, 2020.
