Run cargo update

[spenserblack]

Fixes severe warnings for generic-array and rand_core.

[o2sh]

Thanks for fixing the build @spenserblack, I see that you've updated more than just generic-array and rand_core in the Cargo.lock. Is there a reason for that ? Especially image and libc which would de-sync with the version specified in the Cargo.toml. We should maybe merge #401 and #399 before regenerating the Cargo.lock ?

@o2sh Good catch! That was the result of running cargo update without any additional arguments, which updates all dependencies by default. Now that you've brought it up, I think it's probably best to only update those few dependencies. I'll push up a new branch head.

The remaining audit warnings seem to be upstream issues with tokei's and askalono's unmaintained dependencies, and it doesn't look like there is a new release yet of either that would fix those audit warnings.
