Resolve "update pythermogis (add new jd property)"

# Change log

## v3.0.1 (06-7-2026)

- Added pressureDifferenceGradient as property.

- Implemented detailed SDE classes

## v3.0.0 (20-3-2026)

A big update on the API of pythermogis.

The input to run a doublet simulation is now all well defined on the Python side. With the new UTCSettings, Aquifer/StochasticAquifer and ThermoGISDoublet classes,
