Until now, when '--snthresh' option was implemented on saturated stars all the
pixels in output were NAN. Because in saturated stars all the saturate pixels
were mask in the middle of the star and then the star split into the two
different part. Due to this we could not extract the exact label of the
saturated stars to keep the star and mask other pixels. Finally, the output
was completely NAN.

With this commit, first of all the saturated pixels is filled and then the
label of main stars is extracted properly and mask the other pixels. Although,
at the end all the saturated pixels masked again.

This bug is fixed based on the following command in the Git:
