File naming

Filenames encode the variable and date, e.g.:

prec_20090301_01_00.tif        # precipitation, 2009-03-01
soil_moist_20200918_03_00.tif  # soil moisture, layer 3, 2020-09-18
spi3_20240601.tif              # SPI-3, 2024-06-01

Fluxes use the pattern <var>_<YYYYMMDD>_<layer>_00.tif; drought indices use <index>_<YYYYMMDD>.tif.
