update proportion calculation #36

Closed amsnyder closed 2 years ago

I updated the calculation of the proportion of measurements per day. Previously, I was counting the number of timestamps per day as our expected number of observations. As described in issue #27, it was dropping certain parameters because they were measured less frequently than other parameters at that site. To fix the issue, I counted the measurements taken per day for each parameter individually. I then took the mode of each of those counts to be the expected number of measurements for that parameter. I think used this as the denominator when calculation what proportion of measurements we have available.

That field was put in so that we could specify other time intervals to aggregate over (hourly, weekly, etc. averages). We haven't had a need to do anything but daily yet, so it is the only aggregation level I wrote code for at this point.
