* Implement styled arguments * Inherit from formatter<Arg> to get the underlying `parse` and `format` * Move styled_arg definition into the previous detail block * Change styled_arg ctor parameters names to avoid shadowing members * Move const before auto * Remove redundant constructor for styled_arg * Use the iterator instead of the buffer in styled_arg::format * Remove unnecessary `styled` overloads * Remove defaulted text_style parameter in styled function
