Simplify wqp concentration data

1 2	wqp_simplifyConc(wqpData, average = c("none", "depth", "time"), allowDuplicates = FALSE, redundantUnits = c("purge", "keep"))

`wqpData`	processed WQP data result
`average`	How to average the observations if at all. "depth" will average observations over depth; "time" will aggregate to daily resolution.
`allowDuplicates`	If `FALSE`, remove duplicates using `unique` following simplification.

Note the following behavior when averaging. The is.bdl column is also averaged, and therefore is no longer a logical vector, but a decimal on [0, 1] indicating what proportion of averaged observations were bdl. Some columns are dropped when averaging, namely the ones being averaged over, while one is added, giving the number of observations being averaged.
