B2OC: b2dstkspi and b2dst3h lines, hlt2+sprucing (shifters PLEASE ignore)

Created hlt2 and sprucing lines for the following decay modes:

• B0->D*+K0Sπ-
• B0->D*+K0SK-
• B0->D*+π+π-π-
• B0->D*+K+π-π-
• B0->D*+π+K-π-
• B0->D*+K+K-π-
• B0->D*+π+K-K-
• B0->D*+K+K-K-
• B0->D*+p+~p-K-

with D*+->D0π+, K0S->π+π- and D0->h+h- or D0->h+h-h+h-
