DFDL debugging session

1. Run a DFDL debugging session with "openDataEditor": true,

Example config you could use:

 {
            "request": "launch",
            "type": "dfdl",
            "name": "Wizard Config",
            "schema": {
                "path": "${command:AskForSchemaName}",
                "rootName": null,
                "rootNamespace": null
            },
            "data": "${command:AskForDataName}",
            "debugServer": 4711,
            "infosetFormat": "xml",
            "infosetOutput": {
                "type": "file",
                "path": "${workspaceFolder}/target/infoset.xml"
            },
            "tdmlConfig": {
                "action": "generate",
                "name": "Default Test Case"
            },
            "trace": true,
            "stopOnEntry": true,
            "useExistingServer": false,
            "openDataEditor": true,
            "openInfosetView": false,
            "openInfosetDiffView": false,
            "daffodilDebugClasspath": [],
            "dataEditor": {
                "port": 9000,
                "logging": {
                    "file": "${workspaceFolder}/dataEditor-${omegaEditPort}.log",
                    "level": "info"
                }
            },
            "dfdlDebugger": {
                "daffodilVersion": "3.11.0",
                "timeout": "10s",
                "logging": {
                    "file": "${workspaceFolder}/daffodil-debugger.log",
                    "level": "INFO"
                }
            }
        }

2. Verify the data editor tab shows the base file name and nothing odd happens

The Data Editor tests need to be updated to check for the correct panel tab title. The tests currently still have the test expectation of "Data Editor"
