countme-update-rawdb.sh: handle --start, --all
    
    This commit adds `--start` and `--all` to the `getopt` invocation - they
    were listed in the help text and handled in the code, but I forgot to
    add them here so the CLI would actually accept them. Fixed.
    
    Now you can manually do partial rawdb runs if needed! Like, say, if you
    lost the rawdb during a colo move, but you still have the totalsdb from
    before the move, and you just want to parse the logs since the move...
