[I] Can't aggregate calculation results of the Math processing element (streampipes)

SvenO3 opened a new issue, #1291:
URL: https://github.com/apache/streampipes/issues/1291

   ### Apache StreamPipes version
   
   dev (current development state)
   
   ### Affected StreamPipes components
   
   Processing Elements
   
   ### What happened?
   
   When calculating a new field with the  `Math` processing element, you can only aggregate the calculation result with `First`, `Last`, `Mode` and `Count` in the Data Explorer, but you can't use `Mean`, `Min`, `Max` or `Sum`. 
   
   ### How to reproduce?
   
   Create a pipeline, use a data source with two numerical fields and use the  `Math` processing element to calculate a new field:
   ![math_pipeline](https://user-images.githubusercontent.com/43231162/219004142-7d98ba94-6fd5-4946-a4fd-648ef20e289e.png)
   When you agregate the calculation result with `First` every thing is fine:
   ![aggregated_first](https://user-images.githubusercontent.com/43231162/219004697-3faff523-e2ae-4a36-83ce-8d69e196c8de.png)
   But if you try to show the `Mean` it does't work:
   ![aggregated_mean](https://user-images.githubusercontent.com/43231162/219005030-42ef202a-1801-4e04-b4b9-9ff33a3a89e8.png)
   
   
   ### Expected behavior
   
   Maybe there's an error with the type of the calculation result.
   
   ### Additional technical information
   
   _No response_
   
   ### Are you willing to submit a PR?
   
   None

   I think I know where the problem is, but it might still take me some time to solve... So, you can assign it to me if there is no hurry 😃
