commit 1364e1917750b1515cb1b1662c24bc1080c4ecbf
Author: Arthur de Jong <arthur@arthurdejong.org>
Date:   Sat Nov 12 15:55:35 2022 +0100

    Support "I" and "O" in CUSIP number
    
    It is unclear why these letters were considered invalid at the time of
    the implementation.
    
    This also reduces the test set a bit while still covering most cases.
    
    Closes https://github.com/arthurdejong/python-stdnum/issues/337
