Andy Balholm b2497e8d72 Revert "Use sort.Sort to sort Huffman trees." 
This reverts commit 6b5963335e.

It doesn't really have the performance benefit I thought it did.

Andy Balholm 7c7a5a10ef Push output directly to dst instead of buffering. 2020-05-07 17:27:37 -07:00
Andy Balholm 625cbb6f92 Replace storage_size_ with len(storage). 2020-05-07 15:40:58 -07:00
Andy Balholm f41712f811 Remove unnecessary parameters from encodeData. 
The pointers passed to out_size and output were always the same,
so there is no need to have them as parameters.

Shane Hansen 94370e0b46 Lift structs to higher scope 
Small performance improvement (27%) by re-using search result
structs. Likely the original C version relied on stack allocation here.
