Declare pandas, shapely, pyproj and packaging as dependencies

All four are imported at module scope and sit on the import omniwatermask
path, but none appeared in dependencies. Every install has relied on them
arriving transitively: pandas, shapely and pyproj through geopandas, and
packaging through huggingface_hub, which declares packaging>=20.9.

Nothing has broken, since each is a hard requirement of a package this
project does declare, but the imports would fail the moment an
intermediary dropped one, and that surfaces as a ModuleNotFoundError on
import rather than as a resolver error at install time.

The floors for pandas, shapely and pyproj mirror what geopandas>=1.0
already imposes. Only long-stable API is used from each (pd.concat and
read_csv, shapely.geometry.box, CRS.from_epsg), so declaring less would
not be installable alongside geopandas rather than extending support.

+### Fixed
+- `pandas`, `shapely`, `pyproj` and `packaging` are now declared as dependencies. All four are imported at module scope — `pandas` by `download_models.py`, `target_builders.py` and `vector_cache.py`, `shapely` by `target_builders.py` and `vector_cache.py`, and `pyproj` and `packaging` by `target_builders.py` — so all four sit on the `import omniwatermask` path, but none of them appeared in `dependencies`. Every install has therefore been relying on them arriving transitively: the first three through `geopandas`, and `packaging` through `huggingface_hub`, which declares `packaging>=20.9`. Nothing has broken, because each is a hard requirement of a package this project does declare, but the imports would fail the moment an intermediary dropped one, and the failure would surface as a `ModuleNotFoundError` on import rather than as a resolver error at install time. The floors for `pandas`, `shapely` and `pyproj` mirror what `geopandas>=1.0` already imposes, since only long-stable API is used from each (`pd.concat`/`read_csv`, `shapely.geometry.box`, `CRS.from_epsg`) and declaring less would not be installable alongside geopandas rather than extending support.
