Problem 44293. Write out numbers in words

First time seeing the use of dictionary on Cody. Nice!

@Dyuman thanks! I've actually used them regularly --- a quick grep suggests they appear in my solutions for problems 53, 65, 213, 303, 639, 831, 980, 1203, 1378, 1686, 1696, 1836, 1889, 2147, 2153, 2162, 2186, 2227, 2447, 2508, 2524, 3053, 42316, 42370, 42613, 43668, 44293, 44669, 45262, 45365, 46913, 51675, 52298, and 56623 at least, though the list may be incomplete since I don't have all my solutions saved locally. Of these, solution 9223510 to problem 53, submitted on October 5 2022, is the oldest one I have that uses a dictionary.
