Fix detector build issues

Summary:
Made changes to make some previous components compatible with vizard.

- Modified rotated box to accept additional arguments to support forward compatibility with vizard (arguments are unused)
- Created new config file for testing, don't need to change and revert changes golden config file anymore during devloop
- Added registering my test train datasets to setup function
- Added imports to load components into registries
- **[IMPORTANT TO REVIEW] Modified serializer class for datasets (no longer uses SharedList, read more on what SharedList does here: https://fburl.com/code/23u0ci1z)**
