MR !1085 : Nr mac ssb
-MAC scheduling of multiple SSBs
-Symbol level occupation of VRB map for SSBs
-Multi SSB SIB1 scheduling

MR !1097 : NR_PRACH: nr_du\[\] buffer not filled in High Speed case for both gNB and nrUE
Issue: TC nr_prachsim failed with High Speed(-H) enabled.
While generating NR PRACH for High Speed case : Array nr_du\[\] was not filled for both gNB and nrUE. Added function nr_fill_du() to resolve the issue. 

MR !1107 : Small bugfixes for 5G NR
