Adding Filter_B2OC_bdh_strip34_mdst.py
New script adapted from Filter_B2OC_bdh_strip34.py to have mdst output. And tweaked stripping version for 2018 from stripping34r0p1
to stripping34
as stripping34r0p1
was not working on tests.
NB: Files that have been created and are B02DstmH_D2KsHH_Strip*_Filtering_mDST.py can be ignored. (I'm not sure how to remove them from the MR)
