Add CFR to srsue LTE UL (#3865) 
lte,phy: Add CFR to srsue LTE UL

This commit adds the configuration steps needed to enable
and configure the CFR module for the srsue's uplink signal.
Parsing of the CFR manual threshold has been streamlined.

Robert Falkenberg 3a73d84294 srsran_rf: support dynamic loading of RF plugins 
This adds flexible plugin-like loading of the individual RF
implementations (zmq, uhd, soapy,...) as per availability at runtime.
Unlike before, the binary application is not terminated if the
dependencies of individual RF interfaces are not installed on the
executing system.  To do this, the plugins are not linked by the linker
at compile time, but opened at runtime via dlopen() and dropped in case
of failure due to missing dependencies.

dvdgrgrtt a69fb1d50f ch_awgn: Improve API 
The API of functions srsran_ch_awgn_X was causing confusion between
noise variance and standard deviation. Also, in the complex-valued case,
the noise variance did not take into account the fact that the signal is
two-dimensional.

All uses of these functions are modified accordingly.
