* 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
