Boilerplate combining Kong CLI argument parsing with zerolog logging

A Go package providing boilerplate combining Kong CLI argument parsing with zerolog logging.

Features:

• Config (from files, CLI arguments, and environment variables) is parsed into a struct based on struct tags, powered by Kong.
• JSON-based and pretty-printed logging, powered by zerolog.
• Support for built-time version variables and CLI flag.
• Handles exit codes: 0 for success, 1 for initialization errors (CLI argument parsing or zerolog configuration failures), 2 for panics, and 3 for program errors.
• All logging goes to stdout and unexpected errors go to stderr.
• On errors, a stack trace and other details from errors are shown, powered by gitlab.com/tozd/go/errors.
