We would like to throw exceptions in the event of a decoding error (Huffman or HPACK). This work some-what blocks Issue #2 since proper fuzz testing would only really be nice with some kind of error handling framework. I would like to include the byte position decoding began at as well as how far we read from the byte string before the error was encountered if possible. I think it might also be nice (but not necessary) to include the headers that were successfully decoded up to that point.
