Fix reading defects from json and bottom / top module selection for cold noise induced defects.
- Fixes an exception when reading defects from json files which do not contain entries for every module.
- cold noise induced strip defects are by default only generated for bottom r4/5 modules on A and C side. The option to also or only select top modules was only propagated to the modules of the A side.
