Add D0 -> h l nu HLT2 lines

Add semileptonic charm decay lines. Stems stripping used for Run 2 and from work by @shtaneja, with the help of @mstahl @fsouzade @lpica. Adds

For a follow up MR:

• Implement BDT from inclusive charm lines from Run2 (cc @gligorov @spradlin)
• Determine if persistence of Calo/Velo information is needed
