Enforce code style on CI with rustfmt

[0xazure]

#9 introduces code linting with clippy and running the project's tests. We should take this a step further and ensure consistent coding style in our continuous integration pipeline using rustfmt to ensure consistency.

See https://github.com/rust-lang-nursery/rustfmt#checking-style-on-a-ci-server for a minimal example for setting up rustfmt on CI, as well as this blog post on enforcing style in CI for Rust projects.

I'd say we should assign @biskit1 (Chaya) to tackle this one - this is a good, not stressful issue to help get acquainted with the code base. If and only if they want of course. Trying to issue squat for a buddeh.

lol thanks @Mordax!
The other issue I'm working on (and almost finished with) has given me a chance to familiarize myself with the code base, so I guess that makes things a little easier.

I'll try to tackle this over the next few days/weekend. @0xazure can you assign me please?

[0xazure]

Sure @biskit1 go for it! GitHub won't seem to let me assign issues to anyone other than myself right now, but this one's all yours.

Hey @biskit1 just wanted to check in to see how things are going with this issue. Let me know if you have any questions, I'm happy to help out!

[biskit1]

Thanks @0xazure. Opened other PR and this is next :) Will get started ASAP and keep you posted.
