Crest Factor Reduction feature for the phy layer (#3720)
* Add CFR module to the phy lib

* Add dynamic threshold with PAPR estimation

* Add a CFR unit test, CFR module improvements and refactoring.
Swap the gain normalization before the CFR.

* Add CFR config interface to srsenb

Robert Falkenberg d3eca325f7 Add file-based RF device for rx from arbitrary FILE*
It comes with the following changes:

* Add RF frontend API function "srslte_rf_open_file()"
* Open file-based RF via explicit call of custom
  "rf_file_open_file()", instead of "srslte_rf_open_multi()"
  function pointer as for regular devices.
* Introduce device name "file"
* Introduce new SRSLTE_ERROR_RX_EOF error code
* ZMQ: make update_rates() static to resolve conflicts

dvdgrgrtt 73594cf704 Fix minor bug
SRS_API was used instead of SRSRAN_API. Did not seem to have major
consequences.

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.

Asynchronous NR PHY configuration (#3527)
* Fix a race condition when accessing the NR PHY cfg by the RRC and phy workers.
Rework how the phy cfg is handled, now workers have their own copy that gets updated after a reconfig moving it out of the state class.

* Default initialize sf_len member in sf_worker for consistency.

* Asynchronous NR PHY configuration

* Fix compilation

* Corrected method override and fix unitialised value

* Added carrier equal comparison to avoid aligment byte padding comparison
