Description
It would be nice if it were possible to output to a String directly, rather than having to do a dance with format! and the Display impl. I assume the reason this is not currently possible is because this crate is no_std.

Research direction
Start by inspecting the crate's Display implementation and its no_std configuration. Determine how an optional std dependency could support direct output to a String, and consider the API and compatibility implications; done means callers can output directly without the format! and Display dance while no_std use remains supported.
