### Summary
- [X] Gets rid of the Dtos
- [X] Simplifies the json serializer registration
- [X] Adds a custom `RegionByName` JsonConverter that can look up other regions that have already been registered.
### BREAKING CHANGE
1. **Child regions must appear after their parents in the JSON file**
2. In the regions json file, _"Parent"_ can no longer be just a string. It must be an object that includes the map.
- ```json
"Parent": { "Name": "Britain", "Map": "Felucca" }
```
## Possible Breaking Change
* Reverted regions.json back to RunUO until newer regions are implemented and proper expansion checks are added.
### Other Changes
- [X] Adds `Region.IsPartOf<T1, T2>()` to check for multiple types.
- [X] Fixes regions.json being wrong
- [X] Adds lots of missing regions. **They are not implemented properly yet**
- [X] Adds regions.xml -> regions.json (check ModernUO Discord)
- [X] Adds expansion specific regions.
