HLT2 D0->KS0 KS0 lines moved to ThOr

Giulia Tuci requested to merge gtuci/ksks_thor into charm-thor-hlt2-lines

D0->KsKs HLT2 lines are updated to use ThOr functors.

Since at the moment it is not supported to have contiguous children with the same PIDs but different algorithm inputs, a workaround is used in the LD line to apply different selections to long and downstream Ks (we use D0 -> KL0 KS0 in the descriptor).

The total rate, calculated on the upgrade_minbias_hlt1_filtered sample, is below 100 Hz:
