README.pod: Bump with "ack -h '^=encoding' -A 9001 lib/Hailo.pm > README.pod"
Changes: Make it clear just what a minor release this is
v0.71

    - Super minor release, just docs and nuking an old developer
      script that wasn't even in the CPAN tarball.

    - Bump README.pod with new content from lib/Hailo.pm's POD.

    - Remove unused script that used Class::MOP to close RT #91029
      ("New Moose may break your code")
