The flate library contains generator code, which is used to generate the fixed huffman table. This is done so that fixed blocks can be processed quicker since there is no need generate the decoder table for fixed codes. Instead, delete the precomputed table, and use sync.Once to generate it at runtime when used. Advantages: * Reduces duplicated logic in flate package * Reduces binary size by approximately 2KiB Disadvantages: * For the simplest possible program that simply decodes the fixed block "\x03\x00" once, the modified code takes 4.7% longer for the first decode. Compression performance for subsequent blocks afterwards has no noticeable slow down.
