A refactored version of pybx built using nbdev.

Added:

• documentation page: docs, README.md, example walkthrough file
• GH workflow tests

Breaking changes:

• Need area() and valid() are now properties of BaseBx, so .area and .valid would suffice
• utils methods refactored to utils and ops

In the step: Ask VisBx to use random logits with logits=True

vis.VisBx(image_sz=image_sz, logits=True, feature_sz=feature_sz).show(anchors, labels)

Returns a key error: KeyError: ((1, 1, 3), '<i8') and TypeError: Cannot handle this data type: (1, 1, 3), <i8 with PIL.

• Refactored major sections of pybx.basics and the BxType
• Backwards incompatible!
• Detailed docstrings for all methods and classes
• Directly visualize arrays in VisBx()
• Visualize, iterate, __add__ operations for BaseBx
• Helper function to set and return BxType (get_bx)
• Several verbal assertions and bug fixes
• Fixes #3 #2
• [dev] Updated tests

Describe the bug draw method of vis module tries to iterate over BaseBx during visualisation

To Reproduce Steps to reproduce the behavior:

anns = {'label': 5,
 'x_min': 87.0,
 'y_min': 196.0,
 'x_max': 1013.0,
 'y_max': 2129.0}

from pybx.ops import make_array
coords, label = make_array(anns)

b = bbx(coords, label)
vis.draw(img, b)

Main commits

• implemented intersection-over-union (IOU) for BaseBx
• added unittests for all modules
• Implemented classmethod and bbx() for BaseBx class to convert all types to BaseBx
• ops now handles all type conversions (json-array, list-array)
• bug fixes, best caught:
  • BaseBx method xywh() flipped w and h
  • read keys in order of voc_keys for json annotations)
• updated README.md and nbs/

Is your feature request related to a problem? Please describe. Rather than creating a bunch of anchor boxes based on geometry, create region proposals based on classic signal processing.
