    devtool: add a 'latest-version' command
    
    This command queries the upstream server for what the latest release is and prints
    the output; it is a much neater way to find out these things than fumbling with distrodata,
    'bitbake -c checkpkg' and awkward to read csv output in a file.
    
    Examples:
    
    python3 (tarballs):
    NOTE: Current version: 3.5.3
    NOTE: Latest version: 3.6.3
    
    rpm (git):
    NOTE: Current version: 4.13.90
    NOTE: Latest version: 4.14.0
    NOTE: Latest version's commit: da3720f62e57648fb1dc2a632744d38866139971
    
    puzzles (git without version tags):
    NOTE: Latest commit: ee8ea9b9785964694cb2b3ad77c3fb2460f49510
