v0.4.0

Fixed:

• binarize: OCR-D conformity (PAGE output, AlternativeImage input/output)
• docstrings

Added:

• recognize: param overwrite_text
• segment: param overwrite_segments
• segment: param level-of-operation (now supports table and region, too)

Changed:

• binarize: 🔥 renamed level-of-operation=block to region
• segment: existing segmentation will be masked away (unless overwrite_segments)
