 since PHP8.1, PasswordHash::gensalt_blowfish risk getting E_DEPRECATED
 errors like
 >Deprecated: Implicit conversion from float 48.8 to int loses precision

 in
 ```
 $output .= chr((ord('0') + $this->iteration_count_log2 / 10));
 ```

 ```
 $output .= chr((int)((ord('0') + $this->iteration_count_log2 / 10)));
 ```
