cli: Allow enabling debug via GEMATO_DEBUG envvar

Support using GEMATO_DEBUG envvar to override the log level and force
DEBUG.  This is mostly meant to handle calling gemato executable
via scripts where users can't trivially pass `--debug`.  When gemato
is used via the Python API, the caller needs to configure the logger.
Something akin to the following is recommended:

    logging.basicConfig()
    if os.environ.get("GEMATO_DEBUG"):
        logging.getLogger("gemato").setLevel(logging.DEBUG)

plus passing `debug=True` to `OpenPGPEnvironment` constructors.
