🚀 feat(base.py): add pydantic BaseModel as a base class for FieldFormatter to enable data validation and serialization

The FieldFormatter class now inherits from pydantic.BaseModel in addition to ABC (Abstract Base Class). This change allows FieldFormatter instances to benefit from the data validation and serialization capabilities provided by pydantic, improving the reliability and maintainability of the code.
