reduce disk space usage

Having run the hog for some time, the DB size gets bigger and bigger.

Apart from the fact that this is quite much data for not that much time (month), I feel like at the least we should have the option to delete data that is older than a certain time. Or best case, older data gets aggregated automatically, so we don't have all the details, but still have all the past statistics.

Hey. Thank you for reaching out and pointing this out. I have scheduled a "compress" feature for the next release.
