Update l1a event message test

Pull request overview

Adds support for decoding IDEX event-message packets into rendered, human-readable message strings and writing them to a dedicated L1A “msg” CDF product, along with the needed CDF metadata and updated tests.

Changes:

• Introduces template-based rendering for IDEX event messages using IDEX-provided lookup dictionaries.
• Updates IDEX L1A processing to generate an imap_idex_l1a_msg dataset with a messages variable.
• Extends CDF global/variable attribute configs and updates the L1A event-message test expectations.

That is helpful to know!

The code changes looks good. I had minor requests for variable names updates for easier readability in the future when we don't have much context of the background. Can you make those changes? Otherwise, the code is solid and makes lot of sense!

Looks great! Thank you for making those changes!
