Avoid compiler warning about signedness mismatch

This warning kept appearing for me:

Script.cpp:350:35: warning: comparison of integer expressions of
different signedness: ‘int’ and
‘std::__cxx11::basic_string<char>::size_type’
{aka ‘long unsigned int’} [-Wsign-compare]

  350 |                 for (int i = 0; i < words[1].size(); i++)
      |                                 ~~^~~~~~~~~~~~~~~~~

So I just made it a size_t instead.
