    This functions cuts the given image into pieces(sprites) and returns them as a list of images.
    WARNING!!! It needs the pygame library to be imported and initialised to work.
    Basically this piece of code is to be used preferably within an existing program.
    size is the size in pixels of the sprite. eg. (64, 64) sprite size of 64 pixels, by 64 pixels.
    file_name is the file name that contains the sprite sheet. preferable format is png.
    pos is the starting point on the image. eg. (10, 10) think about it as an offset.
