feat(Blenvy): modifier deep scan is done & huge cleanups

* finished & cleaned up modifier deep scan: works well !
 * now toggleable via a setting
 * same for the deep scan for materials
 * rewrote the very messy materials scan, with a much improved generic_fields_hasher
 * still need to add back an improved material node tree serializer
