Error with SIFT and without flann

[Daniil-Osokin]

Got an error running the example script without flann, to reproduce:

python main.py register --camera_params "CameraParams/CameraParams.npz" --input_image "old_files/andrew photo video/reference messy.jpg" --output_image "output_script_test.jpg" --crop_method "none" --feature_method "SIFT" --model_output "model_script_test.npz"
Skipping image cropping as per the selected method.
Model saved to model_script_test.npz


python main.py detect --model_input "model_script_test.npz" --input_image "old_files/andrew photo video/second pic messy.jpg"  --draw_match

There were problems with parser and detection.py. Im fixing parser and hope Daniil will deal with the problem in the detection
