v0.3.10

• fix: properly kill child processes on Windows
  • A previous commit didn't address Windows. Now process groups are killed properly on Linux, MacOS, and Windows.
• fix: override the expected converted Pub/Sub payload
  • There are multiple legacy Pub/Sub payload schemas. When converting CloudEvents to legacy events there is no information in the CE that enables us to infer which schema to convert to. The conformance test framework assumes the converted output will always match a corresponding unconverted payload, which isn't necessarily possible. There is now a mechanism to override the expected output when converting between event types.
• feat: add a workingDirectory option to run conformance tests in a subdirectory
