How to use Data Formatting feature?

[Timmmm]

There are no examples for how to use the Data Formatting structs. I assume something like this:

let bar = ProgressBar::new().with_format(HumanBytes);

But the only examples are for using HumanBytes directly.

Use them via the templates, like human_len etc?

[Timmmm]

Is that the intention? If so I suggest adding a comment like

This is used by decimal_bytes and decimal_total_bytes in format templates.

to the DecimalBytes struct description (and similarly for the others).

Happy to review a PR for this.
