This is a program that saves and loads images in different formats and compressions.

--HOW TO USE--
Load images with a-s-d-f-g-h-j-k-l-z-x-c
Clear screen with b

Press 1 to select dithering and process options
	Go to the console and choose the option inside it (y/n)
Press 2 to process the loaded image on the left.
	Left is the loaded original image and right is the processed image
Press 3 to save the right image
Press 4 to load the saved image to the left


- File Format:
	Header:
		ID: 2 byte
		Width:       2 bytes
		Height:      2 bytes
		Mode:        1 byte
		Dithering:   1 byte
		Compression: 1 byte
		Data Size:   4 bytes

- Image is read by snaking around. 

- Compression is both byteRun and RLE, whichever is smaller, 
	uncompressed could be smaller as well.
- Input alphabet is 6-bit
- Imposed Palatte:
	6-bit colour data RRGGBB
	
-Dedicated Palatte:
	When an image has less than 64 colours
	The image remains unchanged. Still 24bits
	This file is saved with the same header but after that it has the 64 colour palette. 
		192 bytes of the dedicated palatte, after which the image is saved as an index to the palatte
	Header + dedicated palatte + image indexed to the palatte




What will the code do:
	1- Asks the user if it wants it dithered, Y/N
		1.1 the user is asked what method of dithering, 1 for Bayer, 2 for Floyd-Steinberg
			1.1.1 if 1 dithering mode is set to 1, Bayer 4x4
			1.1.2 if 2 dithering mode is set to 2, Floyd-Steinberg
			
	2- Asks the user what colour mode it should be, 1-2-3-4
		1- imposed palatte
		2- imposed greyscale
		3- dedicated greyscale
		4- dedicated palatte
	
	2.1- If dedicated options are chosen, it checks how many colours there are
		 if when counting it goes over 64 it stops checking and decides it's not dedicated
			gives the user an error and asks again to chose another option
		 if there are less than 64 colours it changes the mode to dedicated options
		 After changing it to the dedicated options, write the palatte to the file
	
	3- IF NOT DEDICATED
	   Snake around and collect the image data.
		 Keep the size of the file for uncompressed
	   Snake around and collect the image data as byteRun ( 6-bit input alphabet )
		 Keep the size of the file for byteRun
	   Snake around and collect the image data as RLE     ( 6-bit input alphabet )
		 Keep the size of the file for RLE
		 
		3.1 Choose the smallest size method. Set the method in the header
			If it is not RLE;
	   Snake around and collect the image data as the smallest method
	   
	   SAVING IS DONE
	   WHEN LOADING JUST READ THE HEADER AND DO THE OPPOSITE CONVERSIONS
