Creating a paletted image along with other images broke it

I will tidy this up in the next few commits

Processing more than one image at once didn't work (quite bodgey)
MCIR would run even without a map
Error handling for map/raw images that don't exist

Allows custom filenames for the output image
Fix formatting in help text

Also improve land color in MCIR images

Add linear equalise
Add image flip for southbound passes
Completly remove old falseclor in favour of a much simplier method

Change calibration to better suit constant gain
Add -Wextra to Makefile
Add link to model of the PLL
Max number of rows for the image is now increasible

Also change palette to something nicer

Add a denoise filter
Fix temperature calibration
Tidy up some files
Improve MCIR
