switch from failure to anyhow

[hdhoang]

HI, for hacktoberfest, I looked at o2sh/onefetch#432 and arrived here. I would like to replace failure crate with anyhow. Are you okay with this direction?

While getting started with cargo t on windows, I found some assumptions in justfile and datasets' symlinks for a unixy environment. Can I find some way to make it smoother on usual, non-WSL windows as well?

Thanks, I hope a drive-by contribution is okay

Sure, both of those sound fantastic and would be welcomed. Thanks!
