Chore: prefer `HashMap::from` rather than collecting `Vec` of tuples

Hello there! Since Cargo upgraded to the 2021 Edition recently (which implies a `rust-version` of `1.56` or greater), I figured now may be a good time to use the new [`HashMap::from` shortcut](https://doc.rust-lang.org/stable/std/collections/struct.HashMap.html#impl-From%3C%5B(K%2C%20V)%3B%20N%5D%3E) of rust-lang/rust#84111. There should be no change in behavior here, but it does make the code a little bit neater! 🎉
