v0.12.0

Added

• If Pydantic is installed, parameter data classes automatically have Pydantic type validation enabled.
• Parameter primitives classes ParamInt, ParamFloat, ParamBool, ParamStr, and ParamNone.
• Parameter file classes ParamFile and ParamDataFrame.

Changed

• All ParamData objects now internally track the latest time that they or any of their children were last updated, which is returned by ParamData.last_updated.
• Param and Struct are combined into a single class ParamDataclass.
