Title: adding the encoding to the dictionary page

I know that I was originally saying this is not necessary. But now that I'm implementing dictionary encoding, I think we should add the encoding to the dictionary page. The reason is that we can have multiple encodings in the same column chunk and it makes more sense from a model perspective to know which encoding is using a given dictionary page.
