A simple Windows command-line tool for cropping multi-monitor PNG "PrtScrn" images down to a single monitor

• C++17 flag is required for compilation (std::filesystem)
• The OpenCV library is needed OpenCV
• The C++11 port of docopt is used for command-line argument parsing docopt
• spdlog is used for logging spdlog
• Platform specific (Windows)

• Crop all multi-monitor PNG Images in the specified directory dynamically based on the given monitor ID.
• -r for recursive directory search.

• Other Image types (instead of using opencv to load each image and check its size, a custom header reader ONLY for PNGs
  is used to read just enough bytes to discern the size).

• Dimitrios Kazakos - Initial work - Gast91
