ULTRA l1b priority 1,2,3,4

[lacoak21]

Change Summary

Closes #2912

Overview

Produce Priority 1,2,3, and 4 DE products. Eventually one of them will be used(varies by pointing) to produce the psets.

File changes

• imap_processing/cdf/config/imap_ultra_global_cdf_attrs.yaml
  • global attrs for priority l1b de products
• imap_processing/ultra/l1b/ultra_l1b.py
  • Add handling for producing l1b de priority products. They are handled in the exact same way that raw de products are handled.

Testing

Test for priority product

Pull request overview

Adds support for generating ULTRA L1B “priority” direct-event (DE) products (priority 1–4) alongside existing DE processing, and updates CDF metadata accordingly so these products can be written with correct global attributes.

Changes:

• Add global CDF attributes for ULTRA L1B priority 1–4 DE logical sources.
• Update ULTRA L1B processing to detect and convert priority DE L1A inputs into corresponding L1B outputs.
• Add a unit test to validate creating an L1B priority DE dataset from an L1A priority input.
