NR UE: add support for multiple RF frontends

This MR adds basic support for multiple RF-frontends at the UE.
There are multiple reasons why we might want this:
1. There might be different antennas needed for different bands (e.g. NTN or
   TN antennas). These antennas might be connected to different RF-frontends.
   In case of Handover, the UE needs to dynamically switch between these
   RF-frontends.
2. Each rf-simulator connection carries baseband I/Q samples. To be able to
   perform a handover between two cells at different frequencies, there must
   be two rf-simulator connections, as the baseband channels should not
   interfere and thus cannot simply be added.
3. When we want to support multiple UE simulation within one instance of
   nr-uesoftmodem, and allow multiple cells and probably even handover between
   these cells, we need either:
   1. dedicated RF-frontends for each simulated UE, or
   2. dedicated RF-frontends for each connected cell and dynamically assign
      simulated UEs accordingly.

This MR implements what is needed for 1., 2. and 3.1.

## running the back-end
To trigger the back-end use the `--websrv` option, possibly modifying the parameters as explained in the [previous section](./websrvuse.md#web-server-parameters). The two following commands allow starting the oai gNB and the oai 5G UE on the same computer, starting the telnet server and the web interface on both executables.
