This library provides several useful constructs to format data in a human-readable fashion with zero allocations

Some of these functions may seem to reinvent existing std functionality: ```rust println!("{}", displayutils::join(&[1, 2, 3], " + ")); // displayutils println!("{}", ["1", "2", "3"].join(" + ")); // std

println!("{}", displayutils::repeat("abc", 4)); // displayutils println!("{}", "abc".repeat(4)); // std ```

The important difference is that the std approach involves 4 allocations, whereas the displayutils approach operates 100% on stack and is therefore nostd compatible and likely faster.

Also, this crate aims to be very generic in its parameters. In many cases, you can pass arbitrary Display objects as parameters and are not restricted to strings.
