Rename this library? (and if so, alternative names wanted!)

Originally I called this `osv-detector` because I felt "auditor" and "scanner" were a bit overloaded, and I was considering if this was to be published as a package somewhere, `osv-detector` would be less likely to have already been taken.

However, I'm now thinking if it would be better to call it something else for a few reasons:
1. ~I'm thinking about additional checks we could be doing, like #75~ (I don't think this is probably worth it)
2. Go packages/binaries are not restricted to unique names, and `osv-detector` might not be as easy to find as say "security-auditor"
3. `osv-detector` is sort of wrong, as this tool isn't for "detecting OSVs"...

But the real blocker for me is what to actually call it instead - I'd prefer to not use "lockfile" (e.g `lockfile-auditor`) because that'd put us back in the same place if we start auditing more than them (but then maybe it's fine?)
