scl_skeleton: Anlagen-JSON als Eingabe (Stufe 4, Namen)

--json erkennt <csv>_anlage.json am Schema. scl_context.HwSource setzt
Namen aus bindings (nur "zugeordnet") und conveyors ein: Separator-,
Lagerlinien-, Weichen- und Vario-Antriebsnamen, #fbCarousel<NNNN> am
Kreisel, Foerderernummer im DB_JamArea-Platzhalter (<k> bleibt offen).
Eingesetzte Namen werden gegen <projekt>_hw.json geprueft (--hw,
--strict bricht ab). --eplan bleibt fuer die TRO-JSON; Templates und
Golden-Files unveraendert.
