V 2.0.0

• A small change in the encoding tables for 8 bits and under results in improved compression with no speed penalty
• Inputs with very small dimensions are allowed. Previously each dimension had a minimum of 4 pixels, now even 1x1 images are properly handled. Images with 16 pixels and under are stored while larger inputs with one dimension under 4 pixels are reordered and encoded
• Incompatible with V 1.x
