Empty Compressed Data Allowed in Data Submission
In `submitData`, the coordinator can submit data with empty `compressedData` in `_submissionData`, which is not a desired purpose of this function and may cause undefined system behavior.\\n```\\nfunction submitData(\\n SubmissionData calldata \\_submissionData\\n)\\n external\\n whenTypeNotPaused(PROVING\\_SYSTEM\\_PAUSE\\_TYPE)\\n whenTypeNotPaused(GENERAL\\_PAUSE\\_TYPE)\\n onlyRole(OPERATOR\\_ROLE)\\n{\\n \\_submitData(\\_submissionData);\\n}\\n```\\n
Add a check to disallow data submission with empty `compressedData`.
```\\nfunction submitData(\\n SubmissionData calldata \\_submissionData\\n)\\n external\\n whenTypeNotPaused(PROVING\\_SYSTEM\\_PAUSE\\_TYPE)\\n whenTypeNotPaused(GENERAL\\_PAUSE\\_TYPE)\\n onlyRole(OPERATOR\\_ROLE)\\n{\\n \\_submitData(\\_submissionData);\\n}\\n```\\n
