+- Updated the code for both NIR Snowballs and MIRI Showers. The snowball
+  flagging will now extend the saturated core of snowballs. Also,
+  circles are no longer used for snowballs preventing the huge circles
+  of flagged pixels from a glancing CR.
+  Shower code is completely new and is now able to find extended
+  emission far below the single pixel SNR. It also allows detected
+  showers to flag groups after the detection. [#144]
