### Processing steps

    1.  Download .nc files from https://doi.org/10.25959/895K-K978 and file in cwd/input

    2.  Run 02_extract_seasonal_means.py
        * Read all krill_biomass_*.nc files from input/
        * Sums all weekly snapshots for:
          - SUMMER for YOUNG LARVAE (spawning occurs in summer)
          - AUTUMN for FREE LARVAE (young larvae have matured to free larvae)
          - WINTER for LATE LARVAE (young larvae are now late larvae)
          - SPRING for JUVENILES (juveniles are no longer in larval stage)
          - SUMMER for ADULTS (juveniles have matured to adults)
        * Reprojects each seasonal stage from EPSG:4326 to EPSG:3031 (bilinear resampling)
        * Stack the five seasonal stages into krill_biomass_seasonal_stages.tif
        * Adds band descriptions for each seasonal life stage
        * Sums juvenile biomass, and adult biomass, across all input months
        * Combines juvenile and adult biomass to create krill_postlarval_biomass_combined.tif
        * Set NoData to -9999 and writes outputs as DEFLATE-compressed Cloud Optimised GeoTIFFs in output/
