Re: GCBNQ2E new checker request / update

https://project-gc.com/Challenges/GCBNQ2E/114221

As predicted in the previous forum thread I had about this, 4 multi's from the year 2000 is not sufficient for the challenge. While I'm not sure the exact number, I'll shift the first subsection of caches from just "2000" to "up until Feb 2001 (inclusive", and then March 2001 - Dec 2001... and then normal (2002, 2003) otherwise. Hoping the checker can continue to exclude travelling caches... if this isn't possible as an idea, let me know, and I'll work to try and come up with an alternative.

Checker is updated, please try again.

Looks great thank you! Hope this one passes
