T43 generation 2: Gromov-Wasserstein word alignment with a homophone-free word code (N 150, epsilon 0.01); method dropped

gw_t43.py now takes the control setting from the SETTINGS environment variable (otherwise unchanged from generation 1).

Fails its control in a second generation, with the easiest case it is built for (one plaintext word per written word, no homophones, 400-word nomenclator, Herbal B's NPE setting with word spacing). Dropped per the brief. A word-level map can't be detected by co-occurrence at this text length, so the absence of one on the manuscript would say nothing; the method is not run on it.word-spacing control 0.039; stream-spacing control 0.00070
