Various fixes for dissection bugs:
- Expert info for CRC 0x5935 got wrongly attached to Slim SSDO packages
- SPDO Data Requests that fit in the last bytes of a frame got missed
- Slim SSDOs got detected, that actually are not Slim SSDOs, to prevent this
in the future, two checks have been added
- The reported length of a Slim SSDO must be larger than 0 (correct
Slim SSDOs allways have at least 1 byte)
- Both crc's must differ from another. There is a very unlikely
possibility, that they may collide, but in such a case openSAFETY
in itself would be flauted by design.
The change was fuzz-tested and randpkt tested, and the checks from src/tools
where run.
