v1.0.0b25

• Fix cases where subgrid elevation could be nan in coastal areas and DEM was not available. This ultimately leads to an error in the land surface model (propagating nans).
• Include a delta approach to account for changes in precipitation and temperature under climate change in creating return period maps. To adjust forcing data to future climate, add the representative_forcing_year argument to setup_forcing in the build.yml to indicate the year for which you want to fast-forward the forcing data.
• Fix a bug where update-version would not write newly created files to files.yml.
