pkcreatect - program to create and import colour table to GTiff image

pkcreatect  is a utility to include a color table to a raster dataset.  You can either define an existing
       color table (ASCII text file) with the option -ct or define a minimum (-min) and maximum (-max) value.

       Attach a grey scale "color" table to image with values between 0 and 100 and create a legend image (anno‐
