Alexander Suvorov 5822475b22 Completely remove all the chunk related code from the encoder and decoder
This change slightly improves compression speed and simplifies further modification of the code.

Explanation:
Additional performance boost is achieved by using linear representation for selectors and storing block selectors in a single uint32/uint64.

Testing:
The modified algorithm has been tested on the Kodak test set using 64-bit build with default settings (running on Windows 10, i7-4790, 3.6GHz). All the decompressed test images are identical to the images being compressed and decompressed using original version of Crunch.
