Please, do not merge this just yet. I think rusty-hooks might be a better choice for this task, as the developer behind it seems to be more known in the rust community. Even though both crates didn't receive much attention recently, I think there's just a bigger possibility that rusty-hook's maintainer would at least respond. I'd like to test how it behaves on my branch with CI first, tho.

After tinkering with it for a while, I don't think it works, as good as I expected. It has problems with detecting the presence of cargo-make. I think we can stick with cargo-husky for now.

I squashed the commits and added the following changes to this:

• used the one line suggestion in the cargo toml
• changed this so it prints a message rather than installing cargo-make as we shouldn't generally force installation of tools on people's machines.
