ICSHWI-21397: Detector config
Closes ICSHWI-21397
This MR introduces the ability to load detector configuration directly from the general JSON file. Once parsed, the RMM API stores the configuration in a DetectorConfig structure. The stored configuration is then accessible to any FEN client
An example of how to consume the DetectorConfig structure to create a detector configuration is available here: https://gitlab.esss.lu.se/-/snippets/197
