The decoder implements a nice trick where a VLC table actually contains
vectors of codewords. However, when it can't be used, this forces to restart
parsing from scratch. By implementing the recommended trick and inlining
the whole VLC code, an interesting speedup as well as object size reduction
can be achieved.
