Added dota2lounge munging

> We need to pull in dota2lounge data to validate a model.
> This data set has matches and what the odds were on them. We'll compare this to our projected odds to see if we can get ahead.
> Need to add devops code to pull this data over time, it is only available in daily chunks.
> Also need to think about representing multiple odds samples over time, since one match can have many different odds before the match.
