[Huffman] Change Decoding/Encoding tree to structs
...
This seems to have a positive impact on the performance of Deflate and BZip2 decompression and compression. It is unclear to me why these two were declared as classes in the first place.

This fixes potential crashes in BZip2 and Deflate when processing truncated data (a corresponding symbolNotFound error will be thrown instead). There is a performance penalty to this fix, though.

I think, this case is covered by DataError.unsupportedFeature, and we don't want redundant cases, since we're trying to minimize the amount of different error types.
