Why can printing to the serial port or format onto a string fail?
Even if cstyle_format returns Result<usize>, we shouldn't always follow suit.

Introduce OwnedStringView
...
A managed String which uses RAII to free its contents. It's not a proper string though, since it's read-only.
So it's a StringView... but an owned one.
Can't be copied automatically, must be either moved or copied manually by calling clone() on it.
