[2.5.0] - 2025_008_009_019_033_011_984801800_America_slash_New_York_2025_W032_006_2025_221_1754782391_984801800

Added

• Get-UnderscoreTimestamp — Generates an underscore-delimited, timezone-aware, nanosecond-precision timestamp string including:
  • Year
  • Ordinal day-of-year (DDD)
  • Hour, minute, second (each zero-padded to 3 digits)
  • Nanoseconds (9 digits)
  • IANA timezone identifier (slashes replaced with _slash_)
  • ISO year/week/day-of-week
  • Unix epoch seconds
  • Repeated ordinal date and nanoseconds for redundancy
• Useful for precise logging, sortable filenames, and machine-readable timestamps with embedded timezone and ISO calendar context.

Removed

• Removed version number from README.md. It was too much hassle.
