p5-Specio: update to 0.47.

0.47     2021-01-29

- Change Specio constraint object's stringification overloading to return the
  type name rather than the default Perl object stringification, which gives
  you something like
  "Specio::Constraint::Parameterized=HASH(0x564d258efb48)". Anonymous are
  special cased to return something you can print.

- All types now overload the `eq` comparison operator. Moose expects types to
  be comparable in this manner when doing role summation. This fixes a bug
  reported by Martin Gruner. GH #18.
