Last Matterport based version

Additions:

• Added exception handling to avoid stopping the inference tool if there are images remaining.
• Added low-memory mode that uses less RAM by loading the image only once in memory and reloading it whenever it changes.
• Added scripts that can be used to manage results easily (gathering specific file of results, gathering stats of a lot of files into a CSV file...).
• Added post-processing methods:
  • Removal of masks on border or "empty" part of an image,
  • Fusion of masks from different classes,
  • Removal of orphan (and parent class masks without child class mask if enabled) masks,
  • Removal of masks without enough area.
• Added method to keep only biggest part of masks if sparse masks are not allowed
• Added pixel precision confusion matrix. Be aware that based on the way it is computed, some errors on overlapping masks could not be represented in the confusion matrix.
• Added method to get automatically the last weight file using %LAST% in the file path. It looks for a similar file path with the biggest number replacing the keyword.

Improvements:

• Improved code readability by factorizing methods.
• Optimized memory usage even without low-memory mode enabled.
• Improved generalization of the different methods.
• Improved tools by adding some features.
• Improved Confusion Matrix readability by representing large numbers with metric prefixes.
• Improved Confusion Matrix by avoiding counting as bad detections masks included in another mask from their parent class.
• Fixed bugs.
