Fix printing of numbers

Previsouly, this template was used for printing "everything" that could
be printed by iostream's operator<<. This has worked well for strings
and int/uint, but it will break when trying to print out bits such as
uint8_t or int8_t, which are type aliases to signed/unsigned char.

Because we want these numbers to be printed as decimal *numbers* instead
of *characters*, fix this by using the std::to_string helper.
