inventory() parses both response formats: slots=1 -> single tag dict (or None); slots=16 -> list of tags from the iso15_inventory_response_t anti-collision struct, each CRC15-validated. Optional request-level AFI filter and client-side DSFID filter. One 16-slot round drops colliding slots (full tree-walk resolution is a follow-up); scan() stays the single-tag convenience.
