Image Randomizer

This is my homework for the intensive Go programming course taught by Tero Karvinen http://terokarvinen.com/2020/go-programming-course-2020-w22/

What this does is it "randomizes" the colors based on the number that is provided by the user. Works with png and jpeg now

Example usage:

./imageRandomizer -f input.png -n 5 -o outfile.png

Compiled binaries can be found in windows/linux folder but to build it yourself you can use:

go build imageRandomizer.go

Orinally i wanted to create a steganography tool but due to time constraints it became an image randomizer. I intend to create a separate steganograpy tool out of this in the future and maybe implement Vigenere cipher tool i have created before.
