v0.3.6 Improved issue type odd_size, minor bug fix and version updates

• Odd size issue
  We use the IQR method now instead of a hard threshold to detect odd sized images compared to the rest of the dataset. According to this, an image is marked as odd sized if size > q1 + 3 * IQR or size < q3 - 3 * IQR, where q1 and q3 are the 25th and 75th percentiles respectively.
• Statistics
  imagelab.info['statistics'] is now updated to provide key statistics like mean, std, min, max, 25%, 50%, and 75% for all the image properties being computed while looking for issues.
• Bug fix
  Image was being resized to zero width/height for blurry issue check, in cases where aspect ratio was unusual.
• CI pipeline
  Version updates for black, flake8 docs requirements and datasets library.
  Added cron schedule for running tests.
