Accepted algorithm:

• nocompress - No compression
• lz78 - LZ78
• xp01 - Invented by myself, only works for UTF-8 encoding
• xp01b - Invented by myself, similar to xp01, binary mode
• xp02 - Invented by myself, combination of xp01 and huffman, only works for UTF-8 encoding
• xp02b - Invented by myself, combination of xp01 and huffman, similar to xp02, binary mode
• huffman - Huffman
• auto - Automatically choose the best of the above algorithms
