Rfsimulator beam reception/transmission

A simplified beam switching simulation for rfsimulator. This works
mainly in 1 gNB - N UEs scenarios. This is not a real beamformer with
antenna, channel and propagation model. The way it works is that the
peers inform each other about the beams they transmit in, and on
reception before channel modelling, the beam data is combined based on
preconfigured rx_beam/tx_beam gain matrix.

Usage:

- Add --rfsimulator.enable_beams to enable beam simulation

- Add --rfsimulator.beam_gains .

    Example list: 0,-5,-10

    Resulting matrix:

    [[0, -5, -10] [-5, 0, -5]] [-10, -5, 0]]

- Add --telnetsrv if you want to control the beams manually. The command
  in telnet is "rfsimu setbeam <beam_map>", where beam_map is a uint64_t
  controling the reception beam and transmission beam. If the
  application is switching the beams automatically the beams will be
  overwritten as soon as the application chooses to switch beams.

Supports up to 64 concurrent TX and RX beams.
