Hot Pixel Removal

Carefully and effectively cleans out impulse noise of any kind from the dark areas of the image. I had a problem finding a good plug-in which would be able to clean out these huge and ugly hot dots that my "carry-me-everywhere" Nikon S6300 camera produces on very high ISO's. I've found nothing reasonably good, so I decided to write it myself.
