p5-Specio: update to 0.42.

0.42    2017-11-04

- The Perl library claimed it provided types named LaxVersionStr and
  StrictVersionStr but they were really named LaxVersion and
  StrictVersion. The names have now been fixed to match the documentation, so
  they are LaxVersionStr and StrictVersionStr.

0.41    2017-11-04

- Fixed checks for whether a class is loaded in light of upcoming optimization
  in Perl 5.28. Fixed by Sprout (GH #12).
