Use the local registry copy instead of asking crates.io about cargo-update

Is that easily traversable? I seem to have at least three versions of the registry and (IME) updating it takes way more time than the current approach does.

The update to the local registry use git. So the time it takes depends on how old your local version is.
I just tested now and doing a cargo search, which update the registry, took ~3s the first time and then ~1s. Doing cargo install-update -la takes ~8s each time, and I think most of it is time spent doing network requests.

For the traversability, I don't know. Looking at the way cargo does it would be a good way to know.

Because I think cargo-update is mainly IO-bounds, another way to speed it up, would be making multiples request in parallel, using threads or async code.

Check out the feat/6-use-registry branch for now, will flesh out tomorrow.
