Gh 125 malaria summary report hrp2 data fix (#126)

* pulling out HRP2 recoding out of IsInfected loop because non-infected people can have HRP2. Fixing he issue where we were comparing threshold against the total HRP2 proteins in a person rather than against HRP2 per microliter of blood in a person.
