#23 (comment 166295)

dep: added kotlinx serialization as a dependency to kpi-calculator/model to be able to provide Serializable data models

feature: changed result type of AdapterResult.kt and its implementing classes to the new AdapterResult.kt.
The benefit is that we have one common result type for all adapters which can be either a success or an Error with a given ErrorType to indicate all consumers what went wrong during transformation.

- applied new package structure to kpiCalculator adapter (inserted kpiCalculator module)
- removed hardcoded dispatcher in ToolRunService.kt

fix: corrected parameter name for interface function to make sure there are no problems when calling the function implementation via its interface.
