applied patch for UE PUCCH TX from Albesmart. changed p-NR-FR1 to 0 (from 20) to reduce SNR on UL. PUCCH is now functional after inserting physicalCellGroupConfig (before and after applying MasterCellGroupConfig)

corrections in PUCCH handling for dedicated configuration on initialBWP. first transmission handling for DL harq processes at UE.

UE Configuration after SIB1 ok, RAR configuraiton/reception ok, Msg3 transmission / reception ok, CU fails when needing to at SRB1

some more fixes that are missed out in previous commits

so that in the next frame when the same harq is not used the UE won't send feedback (this was a bug)
