📣 borb release notes

This release is more of an aesthetic release.

• The imports have been reviewed,
• a lot of code comments have been reviewed (adding parameters where needed)

A new feature (related to redaction) was added.

• FaceDetectionEventListener runs through a Document and triggers _face_occurred whenever a face is detected (in an image)
• FaceEraserEventListener (based on FaceDetectionEventListener) adds the typical (pixelated) blur to any detected face
