Load monitoring data from all sources

Loads monitoring data for a given time range. Data from AirNow, AIRSIS and WRCC are combined into a single mts_monitor object.

Archival datasets are combined with 'daily' and 'latest' datasets as needed to satisfy the requested date range.

  archiveBaseDir = NULL,
  QC_negativeValues = c("zero", "na", "ignore"),
  epaPreference = c("airnow", "epa_aqs")
)
