achizitie import: TVA DVI cu valuta proprie, discount financiar, cote multiple

- TVA-ul de pe DVI poate avea valuta si curs proprii, diferite de ale facturii
  (rand "protejat": rand_dvi/valuta_proprie pe introdc, sparge_tva_protejat).
- Discount financiar pe factura: rand tip_rand='G' (401 = 767), TVA calculat pe
  baza diminuata, marfa si preturile articolelor pe valoarea integrala.
- Factura multi-cota: randurile S, G si T se sparg pe cotele articolelor, cu
  explicatia TVA din familia coloanei si alinierea T -> S.
- Teste noi in utile/Teste/achizitie_import (discount, DVI, cote, e2e).
