NullReferenceException when using the data visualizer on a Serilog/Clef log file

[Numpsy]

Describe the bug
I was viewing a Serilog/Clef log file and tried using the data visualizer tool.
When I tried changing to the Pies tab, a message box popped up about a NullReferenceException with the call stack

Error: System.NullReferenceException: Object reference not set to an instance of an object.

Looking at the source code that the error points to, I wonder if the issue is that the Module property on the log events is null as the Clef parser hasn't set it to anything?

To Reproduce
Open a Serilog/Clef file with the Serilog parser.
Click the Data Visualizer button on the Logs tab.
Change to the Pies tab on the Visualizer dialog

Result: an error message box pops up.

Expected behavior
I don't expect any error messages.

Desktop (please complete the following information):
Windows 10 64bit, Log Viewer 4.2.1.0 on .Net Core.

Thanks for reporting.
I'll check this out.

Edit:I can reproduce it and will fix it soon :)

btw, you are right, Module/Source properties are indeed null as the Clef parser hasn't set it to anything

I'll release new version over the weekend :)
