v1.3.0

New Features

• Added raw data identifier $ to directly use raw data from a response as request body. See the example in the
  documentation for more information. [#66, #67]

• Added a new flag --retry-failed (or -R for short). When a batch execution fails, failed files are now saved to a
  temporary file. After that, goat can be executed again with only the flag which will re-run only the failed files.
