Constructor.
basic_format_context(
format_options opts,
OutputString&& storage);
Move constructs an OutputString
using storage. After
construction, the output string is cleared. Uses an empty error code
as error state. This constructor allows re-using existing memory for
the output string.
Basic guarantee: exceptions thrown by move-constructing OutputString are propagated.
