Detailed Description

Multi-format climate file reader for temperature, evaporation, wind.

Supports four climate file formats:

• USER_PREPARED: SWMM's own whitespace-delimited format
• GHCND: NCDC Global Historical Climatology Network Daily
• TD3200: NCDC TD3200 (NWS cooperative observer)
• DLY0204: Canadian DLY02/DLY04 fixed-format

The reader buffers one month at a time (matching legacy FileData[4][32]). Within a month, lookups are O(1) array access. Month transitions trigger a sequential file read of the next month's data.
