check aggregated zonal vs. gridded - for onset
parsing dates expressed as year throws an error
one of the regression models give biased results


obs reading - add alternative format
check regime algorithm in Neils code
align/check regime map grid vs. data grid
day of year and labelling of years in onset data across the calendar year
change category from onset to agronomic onset
add onset anomaly, climatology, onset dekad, dekad climatology, dekad anomaly
add meaningful file name: onsetA_{datasetID}_{fdate}-{ldate}.nc
why two outputs in computeproductsNoGui()?
add docstring to computeproductsNoGui()

default config from file, not in code, also include deep config entries
