check_for_invalid_stats_in_isnull

[deanm0000]

This is intended to be in conjunction with #16766 to fix #16683 and #15323

There are really two things to fix with those issues. The first, which @nameexhaustion addressed is to stop writing bad stats but the other thing to fix is to have the reader recognize bad stats (ie when the min > max) and then ignore those stats since those files will continue to exist.

I only did one boolean function because I'm hoping there's a way to hoist the check up higher rather than having copy/paste the check in every single function. Also, I probably didn't do it optimally and wanted to get any pointers before doing anymore. I don't think I'll be able to put anymore work into this until at least next week so if someone else wants to take this over then that's fine with me.
