Separate _put arguments for query and JSON-encoded body data in test client; test case showing pydantic model is required for list args

Added option to automatically rotate patches in a nonuniform list such that height is always greater than or equal to width; this is a big data reduction for collections of elongated patches

PatchStack remembers crop boundaries of individual patches if created from list of non-matching patches

Corrected error with overlapping bounding boxes, whereby a second box would overwrite a first; instead, masks are now just additive; also catch case when trying to draw contours from a mask that is a single pixel across

Serialize after running other exports, as patch path is embedded in dataframe; write this with subdirectory

This reverts merge request !16

Exporting patch masks does not automatically make a PatchStack, which forces them to all be the same size
