Challenges:

- Had to hold back GDAL from 3.9 because it's not yet in nixpkgs
   <NixOS/nixpkgs#311310>.
- Had to hold back numexpr from 2.10 because it's not yet in nixpkgs
   <NixOS/nixpkgs#310837>.
- Had to hold back matplotlib from 3.9 because it needs a poetry2nix
   override <nix-community/poetry2nix#1659>.
- Had to force sat-search version 0.3.0 to avoid Poetry downgrading it to
   0.1.0.
- Had to add Cython 0 to the color-operations build inputs
   <nix-community/poetry2nix#1658>.

Script:

```bash
cd flooding/sentinel2_water_extraction
poetry add --lock gdal="<3.9" matplotlib="<3.9" numexpr="<2.10" sat-search=">=0.3.0"
poetry update --lock
git checkout pyproject.toml
poetry lock --no-update
cd ../sentinel1_water_extraction/
poetry add --lock gdal="<3.9"
poetry update --lock
git checkout pyproject.toml
poetry lock --no-update
```
