Solve 2024:2 p1-2 "Red-Nosed Reports"

DDOS of adventofcode.com, did not get to open the
puzzle until 06:05 (five minutes local time).

Screwed up the zip() and lost valuable minutes by
trying to replace it with itertools, only to find
I have made a typo (did AB CD EF instead of AB BC
CD).

I also lost valuable minutes by tring to solve p1
with one nested loop. Stupid.

For part 2, I created the issafe() helper to be
able to remove items from reports and test, one
at the time.
