[Feature]: TC analysis should support TC tracking data that is spread across multiple files #1002
Description
Is your feature request related to a problem?
Current Situation: Tropical cyclone (TC) tracking (i.e. via TempestExtremes) on high-resolution E3SM simulations (e.g., ne120 grid) is computationally expensive. Tracking storms over 10 years of output data can take ~80 minutes. Currently, e3sm-diags does not support reading TC track data spread across multiple files. Instead, users must: Either rerun the full tracking workflow to regenerate a single merged file each time.
If an analysis fails or needs to be repeated, users must rerun the entire tracking process from the beginning. This is inefficient and wasteful, especially for high-resolution cases.
Proposed Capability:
Enable e3sm-diags to accept and process multiple TC track files (e.g., one per year) as input without requiring a single merged file. zppy needs some update as well.
