Florian Kaltenberger 6db55b2f24 - UE channel estimation no longer done in slot_fep. Also created dedicated memory for channel estimates of different channels 
- using nr_extract_dci_info instead of nr_generate_ue_ul_dlsch_params_from_dci as in phy_procedures_nr_ue. The latter was only a (poor) wrapper and not doing what the name suggests. also with FAPI things have to be done differently now. This will come in a next commit.
- other minor changes to remove warning
