- A lot of files have been touched but most of this is changing FPayload::IsValid to !FIoHash::IsZero, the main changes are in EditorBulkData/EditorBulkDataTests
- The only difference between FPayloadId and FIoHash is that the former considered the hash of an invalid or empty buffer to be 'invalid' too where as FIoHash would return a valid hash
-- To keep behaviour the same, we only hash payloads in EditorBulkData using a utility method ::HashBuffer which will not hash empty or invalid payloads and return a default FIoHash instead.
-- Unit tests have been extended to prove that the behaviour has not changed.
