Improvement Request: totalSupply on pairHourData

[dmlayton]

Could we get totalSupply on the hourly pair data? It looks like the data is available and you just need the corollary to this line pairDayData.totalSupply = pair.totalSupply in updatePairDayData to updatePairHourData and whatever other bookkeeping is needed for a new attribute.

I don't have this running locally or I'd do a pull request,

Looks like there is already a PR from a couple of months ago.
