This PR extends formatting for Decimal objects to support underscores as thousands separators (as described in PEP 515). Previously, Decimal only supported commas as thousands separators, while int and float support both commas and underscores.

This will break tests for vendors that de-bundle mpdecimal and use the upstream version. Fedora/CentOS/RHEL are not affected but Debian/Ubuntu use standaline libmpdecimal.

This will break tests [...]

Darn. Thanks, @tiran - my instincts were telling me that we shouldn't modify libmpdec directly, but I failed to figure out why it was a problem.

Closing here; let's continue discussion on the issue.

Re-opening as a proof-of-concept draft PR to show one possible way that we could take this forward without touching libmpdec.

Closing. This has served its purpose as a POC. I'm not likely to have time to turn it into a production-quality PR any time soon.
