added new parameter to L1 section of configuration file, tx_amp_backoff_dB, which provides the backoff from full-scale output at the L1 entity (frequency-domain samples). Default is, 36 dBFS, which is the correct value when using the OAI RU entity. For O-RAN RU, this value should be set according to the O-RU manufacturer requirements. For example 12 would corresponding to 14-bit input level (6 dB/bit).
