Add divide-by-zero panic messages

[tech6hutch]

This brings it more in line with std's numbers, and lets the user actually know why it panicked.

I hope I targeted the right branch, by the way. I was using the version on cargo, v0.2.6, when I noticed the lack of panic messages.

Thanks for this cleanup!

The master branch is good -- I hope to wrap up 0.3 "soon". 🤞

I've made a few bugfixes on 0.2 in the meantime, but I don't think I'd bother just for a diagnostic.

I did these changes from the GitHub editor, which is why there are so many commits. I assume you squash and merge anyway?

I use a bot that does a plain merge, without squashing. I prefer to allow that PRs may have a series of meaningful commits, but in this case the separate commits are not helpful. So it would be great if you could squash this branch, or I can quickly do so myself.

It'd be easier for you to do it, please. Thank you.

Thanks again!
