Message:

Replace the image reading methods in MapillaryUtils by the new ImageUtil class

Changes to the previous behaviour:

  • directories are now recursively traversed instead of reading only the top level
  • JPG- and PNG-files are now recognized by their magic bytes instead of the file extension
  • the number of publicly visible methods for image reading has been reduced to one, which can process both files and directories as well as JPGs and PNGs
