Feature Request: cargo scaffold + cargo download

[alexfertel]

Thank you for creating this template!

I have a very small request for a nice-to-have feature. After setting up my local copy of the template, l find myself running cargo scaffold <day> and, right after, I am running cargo download <day>.. I think a new flag to cargo scaffold like --download or even a separate command like cargo generate <day> that combines both steps would be nice.

What do you think?

I think this is a good idea and would accept a PR for this.

The scaffold --download flag seems like a good way to go about it and is less work to document than a separate command.
