This is step 4 of the lossy encoder as in #155
This PR adds the actual vp8 encoder that encodes images.
There's quite a few changes in this one but I'm not sure how to split it up in a way that makes sense. I did simplify it a little by making it always picking luma mode and chroma mode of DC.
Most of the changes are in vp8_encoder which is similar to vp8.rs but does the reverse operations by encoding instead of decoding.
