- Fix the tests to accomodate the new 1-digit format for days of month

  and run one test per sample date in t/sample.t

- New maintainer - Philippe Bruhat (BooK)

- Now depends on DateTime 0.18. RT #74580.

- Moved POD tests to the release stage.

- format_datetime() now uses 1-digit numbers for day of month < 10.
  Dates with unrecognized timezones lead to the creation of a DateTime
  object with a floating timezone.
  UTC is now formatted as +0000, floating is formatted as -0000.
  RT #94556.

- Now packaged using Dist::Zilla. Moved back to three-digit version numbers.
