[lacoak21]

Change Summary

closes #3174
closes #IMAP-Science-Operations-Center/sds-data-manager#1303

Overview

Decom each l0 packet file, concat all of them together for each IDEX product type, and filter out events that are not in the 10-day window.

File changes

• replace all -1week descriptors to -10days
• Process a list of l0 files and concat and filter them.

Pull request overview

This PR updates the IDEX processing pipeline to use 10-day window descriptors (replacing -1week) and adds multi-file L0 ingestion for L1A so multiple packet files can be concatenated and filtered into a single 10-day output window.

Changes:

• Renames IDEX product descriptors from *-1week to *-10days across processing, CDF global attrs config, and tests.
• Adds idex_l1a(packet_files, start_date) to parse multiple L0 files, concatenate per product type, and filter epochs to the configured 10-day window.
• Introduces an IDEX-provided 10-day window lookup CSV and helper get_10_day_window_end_date() to determine window end dates.

code changes looks good. I didn't look closely at tests.
