Stop using byteorder dependency #83
Description
Infosec managers demand as few dependencies as they can for their checklist. Thus, the byteorder dependency should be removed.
When the byteorder crate was created, it did something that wasn't easily possible without it. Since then, the Rust standard library provides methods like u32::to_le_bytes() and thus the byteorder crate is less useful than it originally was.
Consider removing that dependency.
