	int "Number of predicted maximum entries to main response map"
	default 15
	help
	  This is number of predicted entries in main response map,
	  the one that encapsulates everything within response.
	  This value is used by zcbor to predict needed map encoding,
	  and does not affect memory allocation or usage.
	  Builtin command processors rarely add large amounts of
	  data directly to main map, creating sub-maps instead so
	  the default value works fine with them.
	  If your app directly adds fields to main map, without
	  encapsulating them, you may want to increase this value
	  in case when encoding starts to fail.

	help
	  This is a maximum number of levels of maps/lists that will
	  be expected to be decoded within different command groups.
	  SMP commands/groups that provide no CBOR encoded payload
	  have no requirements.
	  Commands that provide CBOR payload require at least 1 level,
	  and additional levels for each map/list encapsulation.
	  For example if command accepts payload of map of parameters
	  it will need 2 levels.
	  This number translates to zcbor backup states, it increases
	  size of cbor_nb_reader structure by zcbor_state_t size per
	  one unit selected here.
