Another Code from the Age of Louis XIV

I added another code as item (11) in "French Ciphers during the Reign of Louis XIV".
Unlike other ciphers at the time, it employs numbers up to 100 (not 99) as well as other letter-letter or figure-letter combinations such as "aa" (Avantage), "2a" (bla), "bc" (la), "maniere" (bl).
