Add group_id to Level 3 associations about jwst HOT 2 OPEN

Comment by Jonathan Eisenhamer on JIRA:

Current association pools have columns for all the required data:

        meta.observation.program_number -> program
        meta.observation.observation_number -> obs_num
        meta.observation.visit_number -> visit
        meta.observation.visit_group -> visitgrp
        meta.observation.sequence_id -> seq_id
        meta.observation.activity_id -> act_id
        meta.observation.exposure_number -> exposure```

Comment by Jonathan Eisenhamer on JIRA:

Proposed solution

Each member will have a new attribute, group_id. The value of this attribute will be a string with the following format, as derived from the referenced code in the description:

jw_<program><obs_num><visit>_<visitgrp><seq_id><act_id>_exposure

Though this is specific to NIRCam, the proposal would be to add this globally to all members. There is no harm in the extra information and will future-proof if other cases need this attribute.
