Replace humantime with cyborgtime

[oherrala]

humantime seems to be unmaintained and cyborgtime is fork of it. This change shouldn't affect end users. E.g. "humantime" feature is kept as is.

I also introduced "cyborgtime" feature that currently works same as "humantime".

This kinda looks like you're replacing one unmaintained dependency with another. cyborgtime was forked ~2 years ago, had a few commits and then hasn't seen any activity since. It doesn't seem like the right play here?

On the other hand, bringing in something like Jiff (or even chrono or time) seems a little heavyweight for this. I'm not sure there is really much of a middle ground other than sticking with humantime. Then again, I think this is optional (albeit enabled by default), so maybe it's fine.

I'd evalwate switching to jiff. While its heavier, for the use case, I figure its more likely to be used by other dependencies in the future.

I'd keep the feature name as humantime as that also works as a description of behavior and not just a crate name.

In the future, maybe we should make this feature non-default.

@epage @BurntSushi I made a jiff version in #352.
