Missing ionosphere phase estimation method in RUNW and GUNW products metadata

[vbrancat]

The InSAR workflow currently supports four different algorithms to estimate the ionosphere phase screen of NISAR RUNW and GUNW products (see here). However, the RUNW and GUNW metadata only support three of these methods (see here). This creates an inconsistency between the available ionosphere phase estimation algorithms in ISCE3 and the metadata schema.

Expected behavior: The metadata for RUNW and GUNW should be updated to support all four ionosphere phase screen estimation methods, ensuring consistency with the schema and the current ISCE3 implementation.
