Jonas Karlsson 28ecb523ce Improve KTX file reading memory safety
* Use qAddOverflow/qSubOverflow methods for catching additions and
  subtractions with overflow and handle these scenarios when reading the
  file.
* Add 'safeView' method that checks that the byte array view constructed
  is not out of bounds.
* Return error if number of levels is higher than what is reasonable.
* Return error if number of faces is incorrect.
* Add unit test with invalid KTX file previously causing a segmentation
  fault.
