Subject: [PATCH] Fix clang -Wsign-conversion warning in grisu_count_digits.
 (#1573)

grisu_count_digits is only used by grisu_gen_digits, which assigns the unsigned result to a (signed) int.

Although grisu_count_digits always returns a positive integer this keeps its return type in sync with the type its result is assigned to.
