fixes a definite use-after-free and likely avoids some other potential ones - std::string will convert to a std::string_view automatically but as soon as the std::string in question goes out of scope it is already freed and the string_view is pointing at freed memory - this is *mostly* fine if its returning a reference to the tokenizer's internal vocab table but it's, imo, too easy to return a reference to a dynamically constructed string with this as replit is doing (and unfortunately needs to do to convert the internal whitespace replacement symbol back to a space)
