Add stac_resource_from_process.

@soxofaan , would this be an ok way to solve this?

[soxofaan]

yes that would solve it, but I'd like to avoid an explosion of these ..._from_process convenience methods (e.g. we'll also need comparable variants for vector cubes, MlModel, and there are also variants ..._from_flat_graph, ..._from_json, ...).

I'm wondering if the "UI" can't be simplified to a single Connection.process() method that handles all that automatically
e.g. something like

class Connection:
    ...
    def process(self, process_id, ...):
         if "process returns raster cube":
              return DataCube(...)
         elif "process returns vector cube":
              return VectorCube(...
         elif "process returns Stac resource":
              return StacResource(....
         ...

Ok if I put that in a ticket for later and already merge this?

This is the current workaround:

stac_resource = StacResource(
  graph=PGNode(
      process_id="run_cwl_to_stac",
      arguments={
          "cwl_url": "https://raw.githubusercontent.com/cloudinsar/s1-workflows/refs/heads/main/cwl/sar_slc_preprocessing.cwl",
          "context": input_dict_belgium_vv_master_outside_preprocessing,
      },
  ),
  connection=connection,
)

Later, CWLs should be runned with run_udf, so there is no need for this yet.
