Did anybody even use it anyway?

Exported functions and types prefixed with apt_
  Callback added for getsample, instead of calling named function.
  Allow library to be built without libpng or libsndfile.
Add support for building with MSVC on Windows.
Fix a few MSVC compiler warnings.
Fix nonlinear radiance correction for NOAA19.

Was opening PNG files (which are binary...) with `r` instead of `rb` which caused problems on windows
Added `libsndfile-1` back into FindLibSndFile.cmake, since it's needed
Package `sndfile.dll` instead of `libsndfile-1.dll` since thats what the binary looks for

Create a copy of the image before modifying it for temperature calibration

Contains a variety of data and specifications for the polar orbiting satellite series

Passes are flipped when northbound, not southbound

I will tidy this up in the next few commits

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

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

Add the ability to open a map overlay generated by wxmap (still unstable)
Remove the ability to turn off calibration
Add MCIR images
From now on large changes to neaten up the codebase will be taking place

Also made some floating-point math more explicit

Improved commenting in dsp.c
Updated copyright notices
Code tidy up in some parts

Now RGB based instead of HSV based, this also includes a new RGBA compositing function which cleans up the code responsible false color significantly.

Color palettes have also been moved into 1 file instead of 2
