Handle Git issue 766

[ckormanyos]

This PR is intended to handle Git issue #766.

I hit the wrong button earlier and mistakenly merged the relevant changes to develop without running CI/CD. Oops. I havn't done that one in a while.

So I'll revert the changes to develop and follow up with this PR only.

Hi @jzmaddock I'm attempting to repair this by:

• Clear leading zeros in constexpr suffix initialization via normalize().
• Make the normalize() method to be constexpr.

If you get a chance, could you take a look? Thx

I've still got to handle some issues from boost inspect. Other than that, it's cycled green

OK These seem to be done. I think this one is ready to go.
