LibGfx/WebPWriter: Remove two obsolete comments

Browse source 
In an early version of the huffman writing code, we always used 8 bits
here, and the comments still reflected that. Since we're now always
writing only as many bits as we need (in practice, still almost always
8), the comments are misleading.
