S1c update

[oberonia78]

This PR upgrades our core SAR dependencies and adapts the RTC-S1 workflow so we can ingest and process Sentinel-1C data.

Package	Old version	New version	Rationale
s1reader	0.24.0	0.25.0	Updates s1reader. However, this update does not impact on the RTC-S1.

Just realized that CI failed =/

[oberonia78]

@gshiroma I think the failure is like

          raise AttributeError(
                f"`np.{attr}` was removed in the NumPy 2.0 release. "
                f"{__expired_attributes__[attr]}",
                name=None
            )
E           AttributeError: `np.string_` was removed in the NumPy 2.0 release. Use `np.bytes_` instead.

So, I think we can resolve the issue after merging your PR #91 . I'll further investigate the other issues.

That makes sense. Thank you, @oberonia78 .
