After quality control has been applied to an AIRSIS tibble,
we can extract the PM2.5 values and store them in a data
dataframe
organized as time-by-deployment (aka time-by-site).
The first column of the returned dataframe is named 'datetime'
and
contains a POSIXct
time in UTC. Additional columns contain data
for each separate deployment of a monitor.
airsis_createDataDataframe(tbl, meta)

AIRSIS meta dataframe created by airsis_createMetaDataframe()
A data
dataframe for use in a ws_monitor object.
