Function to change classe on the fly, adding the functions defined in the new class to the current object.

Patch: use the IDC for the set_size and set_resolution functions ; pass the parameter for the recursive call

Update the function with the get_latent_diptych function for the two images on the left, augmented by the quality map

Check if the minutiea is empty (i.e. if the 9.012 field ends with a US caracter, the split function will take the "data after" the last separator (i.e. nothing) in the return list)

Patch : if the FS separator is not present, the minutiae extraction will not fail (the type of the last minutiae will be correctly extracted)
