- Added Cloneable deep clone source generator nuget package

- Configs are no cloned using generated clone, not by serializing/deserializing
- Arrays/Lists (collections in geneeral) are still not cloned properly
- Removed GetRawData from config as it is no longer needed, new clone is very fast
- Added ICloneable<T> which all configs implement
- Cleaned up config classes/code
