do not include "Temperature, sample" characteristic from WQP

[limnoliver]

We pull this characteristic, but I think it is the temperature of a water grab sample. Note really cold temperatures throughout the year:

sample_data <- readRDS('1_wqp_pull/out/wqp_data.rds') %>%
 filter(CharacteristicName %in% 'Water, sample') %>%
 mutate(doy = lubridate::yday(ActivityStartDate) 

ggplot(sample_data, aes(x = doy, y = ResultMeasureValue)) +
 geom_point()

For now will remove these after the WQP pull (in munge_wqp_files.R) but we should remove this from the WQP pull params.
