module to report on prerequisite versions during automated testing

 The Dist::Zilla::Plugin::Test::ReportPrereqs plugin adds a
 t/00-report-prereqs.t test file. It reports the version of all modules listed
 in the distribution metadata prerequisites (including 'recommends',
 'suggests', etc.). However, any 'develop' prereqs are not reported (unless
 they show up in another category).
 .
 If a MYMETA.json file exists and CPAN::Meta is installed on the testing
 machine, MYMETA.json will be examined for prerequisites in addition, as it
 would include any dynamic prerequisites not set in the distribution metadata.
 .
 Versions are reported based on the result of parse_version from
 ExtUtils::MakeMaker, which means prerequisite modules are not actually loaded
 (which avoids various edge cases with certain modules). Parse errors are
 reported as "undef". If a module is not installed, "missing" is reported
 instead of a version string.
