@falbrechtskirchinger PTAL - 32 bit support is now also enabled.

[falbrechtskirchinger]

Welp. I hoped you'd merge one of my 32bit PRs into this one first before I'd do a final review.

The addition of readability-simplify-boolean-expr triggers a bunch of errors on my system with a recent Clang 15 build. Specifically in HEDLEY_(UN)LIKELY.

[nlohmann]

Oh, sorry. But readability-simplify-boolean-expr is excluded. In this PR.

I wished Clang-Tidy was more flexible and one could define a list of sources that you care about and treat warnings outside these files as out of scope. If I had a stupid Boolean tautology checked in "my" code, I would act on it. But not if it's the consequence of piling up calls from different libraries...

Agreed.

Everything else looks mostly good. The bool() cast could probably have been removed entirely. std::conditional doesn't do that, I'm sure.
