258-wide Huffman sub-tree about zlib6502

[pfusik]

This fix costs 16 bytes of code, 1 byte of uninitialized data and 8% speed.

There is one more case that needs to be handled well: codes longer than the 256+ codes of identical length. I think I handled it correctly, but I would greatly appreciate a sample stream with this property.

I don't quite understand the test case you need. In code258.bin.gz there are 258 symbols with 10 bit Huffman codes. Would you like, say, 258 symbols with 12 bit Huffman codes? Or even 15 bit Huffman codes?

Incidentally, I use https://github.com/madler/infgen to examine deflate data. It is very handy.

What I ask for is, for example, 258 10-bit codes and 3 11-bit codes.

Thanks; I get it now. Shouldn't be too hard to create an example of that.
