Add a token count that excludes "Console.Write"s, making it easier to work within the token constraint while debugging

[alice-lefebvre]

The total count is still always displayed. This count is only visible when it differs from the total, and doesn't affect the limit exceeded message.

Code is not great nor robust, just a convenience tool.

I believe this counts as an API change, and therefore is not likely to be implemented since it is after August 1. I suggest closing this PR.
