Create shared diagnostic tooling for XBRL calc mismatches

[jdangerx]

We compare the calculated & reported values in our XBRL data in a few different places.

It would be nice if these comparisons could share code, though if the diagnostics differ wildly that may not be practical.

1. there is one piece of shared code that we can add new diagnostics to

@zaneselvans or @cmgosnell you all have a branch for this, right? Where is it at?

[zaneselvans]

The first part of this was under #2880 -- just getting all of the calc checks to use the same function. @cmgosnell also has #2886 but it sounds like we might be moving in another direction with getting those calculations untangled.

I'll create a new branch / PR that's linked to #2872 that tries to get new metrics in there and maybe separate the steps of the performing the calculations, checking how accurate they are, and generating the corrections.

I think since #2880 is merged, and the rest of the "metrics stuff" lives in #2872, we can close this issue.
