Remove unmactched features from the h5 file and from COLMAP database after the matching is completed #30

When using a dataset with a high number of images the features.h5 file and the COLMAP database can become very large as there will be a huge number of features, even though they have no matches (features.h5 can reach also tens of GB). After the matching is concluded, the features with no matches should be deleted from the h5 file and from the COLMAP database (this can be done just before exporting the features from the h5 to the colmap databse).
