setting_version has benn updated to "21"
XML file "product_to_id.json" has been updated because "STRATEO3D" is noww a brand of 2 machines : DUAL600 and IDEX420
IDEX420 is a "IDEX" machine, so we created 3 definition files : 1 main file "strateo3d_IDEX420" and 2 inherited files "strateo3d_IDEX420_duplicate" and "strateo3d_IDEX420_mirror"
materials PA6CF and PA6GF added to both machines in quality folders
