Options IO

[mdw771]

Features/fixes

Added routines to export Options objects' contents to dictionaries, and to import contents into Options objects from dictionaries

• PtychographyTask has 2 new methods: get_options_as_dict returns a nested JSON-serializable dictionary of the master Options objects and its sub-options; load_options_from_dict populates values of self.options and its sub-options -- self.data_options, self.object_options, etc., with a dictionary.
• Each Options class now has get_dict and load_from_dict that does the same.

The export methods only export non-data fields, i.e., fields that are not large NumPy arrays or PyTorch tensors. These include:

• DataOptions.data
• ObjectOptions.initial_guess
• ObjectOptions.valid_pixel_mask
• ProbeOptions.initial_guess
• ProbePositionOptions.position_x/y_px
• OPRModeWeightsOptions.initial_weights
