danforthcenter/plantcv: PlantCV v3.2.0

PlantCV v3.2.0 adds new functionality and fixes several bugs and usability issues. Summary of changes: Added functionality to the plantcv.print_results function. It now allows users to print the data returned, naming the .txt file whatever they would like. Added complete scripts at the bottom of each PlantCV tutorial in the documentation. Added new function plantcv.roi.multi, allowing users to specify parameters for a grid of regions of interest (ROIs) or supply a list of centers for ROIs if they are not in a grid arrangement. Restructure the way plantcv.analyze_* functions return outputs. Each function now returns the images so the user can save them. Enhancements to the plantcv.pseudocolor function including the addition of an "image" background option, adding the option to turn off titles/axes and colorbar, and an auto-crop option. Changed Matplotlib import (now imported globally in plantcv.__init__.py), fixing the non-fatal warning from setting the matplotlib backend multiple times. Added debug mode to plantcv.analyze_color function. plantcv.analyze_bound_horizontal was previously determining line position differently than the rest of the functions in PlantCV. Instead of line_position=0 signifying the bottom of the image, it will now signify the top of the image. Add a line_thickness graphics options to the params class so users can change the line thickness for the functions plotting lines onto images (analyze_object, all ROI functions, analyze_bound_horizontal, analyze_bound_vertical, acute_vertex, x_axis_pseudolandmark, y_axis_pseudolandmark, scale_features, roi_objects, object_composition). Add a link in the table of contents to the PlantCV Hyperspectral subproject documentation. Add an "image" background option to the plantcv.auto_crop function. Improved code testing coverage to 100%. Allow string arguments to be case insensitive. Added a new option to roi_type in plantcv.roi_objects which allows only the largest contour to to be kept. Standardize argument order and naming across functions. Updated functionality of the plantcv.plot_hist function, including adding an optional mask argument and allowing users to save histograms
