Some test coverage, those that are failing are because of issues propagating nested parameters to pydantic models

Combined all export products into a single call, which routes individual products' export methods and parameters

Fixed bug where error was raised generating 3D patches where expanded 3D stack encountered min/max of range

Adapted base segmentation worklow and API endpoint for generic semantic segmentation model; made dummy model this type too

Added superclass for instance segmentation models and modified ilastik object classification to inherit from it

Added superclass for semantic segmentation models and modified ilastik pixel classification to inherit from it

Added superclass for semantic segmentation models and modified ilastik pixel classification to inherit from it

Renamed ZMask to RoiSet, prototyped object classification methods that add classification result as a dataframe column

Delegated export of patch products to ZMaskObjectTable class; consolidated both batch runner and API-facing workflows into infer_object_map_from_zstack(); consolidated parameterization of export products into pydantic model
