Bug: Compatibility issue with latest eclipse version (2023.3)

[laurent-galvani]

In eclipse 2023.3, it is possible to include .udq and .udt files.
for a user, it creates a GSATPROD keyword in the schedule file that includes keywords and not only numbers (see image).

The eclipse simulation run is working fine with this new functionality.
ECL2CSV (at least the PVT one) forward model is failing. The error message is the following.
