Improve the regularization term

[ShiyuBanzhou]

To resolve this #286 issue, it is recommended to replace the original code containing the inefficient regular expression with the following optimized version:

return url.replace(/^[\u0000-\u001F\u0020]+$/ug, "");

This alternative simplifies the regular expression by removing the redundant | (OR) operator, effectively resolving the inefficient backtracking behavior. This optimization prevents potential performance degradation when handling specific inputs, ensuring more efficient processing.

As you can see from the failing tests, the regexp you propose is not identical. Please add a new comment if you are able to fix it to pass the tests.
