1. Adding a "SL" frequency for Sidelink mode. The importance of this variable is to ensure that when we are in mode 1 (UE+UE+gNB), that the slot configuration and frequencies do not overlap. This SL frequency is important for rotation and allows us to utilize the OFDM modulation and demodulation functions that already exist in OAI. 2. Adding sl_mode to the command line for proper UE deployment when in SL mode. sl_mode can be set to 0, 1, or 2. sl_mode 0 indicates no-Sidelink at all, mode 1 is gNB, UE, and UE (3GPP defines mode numbers). sl_mode 2 indicated UE to UE communications with no gNB at all. 3. New functions for calculating the carrier frequency for SL mode.
