Add more timeframes to flash loan totals

[psybull]

Currently, the FlashLoan info for each token only shows total cumulative volume.

Now that there is a small but consistent flow of flash loans, I'd like to see the 1 day/week/etc breakdown of FlashLoan totals alongside the all-time total.

Obviously not useful for a lot of the markets, but would be awesome for ETH and DAI, at the minimum.

Thanks!
