	Register a metric with the context.

int	nrf_edgeai_obsv_deregister (nrf_edgeai_obsv_ctx_t ctx, nrf_edgeai_obsv_metric_t metric)
	Deregister a previously registered metric.

int	nrf_edgeai_obsv_reset (nrf_edgeai_obsv_ctx_t *ctx)
	Reset inference counters and all registered metrics.

int	nrf_edgeai_obsv_update_probs (nrf_edgeai_obsv_ctx_t ctx, const float probs)
	Feed one inference result to all registered metrics.

int	nrf_edgeai_obsv_update_features (nrf_edgeai_obsv_ctx_t ctx, const float feats, uint16_t n)
	Feed one extracted-feature vector to all FEATURES-source metrics.

int	nrf_edgeai_obsv_for_each_metric (nrf_edgeai_obsv_ctx_t ctx, nrf_edgeai_obsv_metric_cb_t cb, void user)
	Iterate over all registered metrics under the context lock.

size_t	nrf_edgeai_obsv_encode (nrf_edgeai_obsv_ctx_t ctx, uint8_t buf, size_t max_len)
	Encode all metrics as a CBOR blob under the context lock.

size_t	nrf_edgeai_obsv_encode_list (nrf_edgeai_obsv_ctx_t const ctxs, uint8_t n, uint8_t *buf, size_t max_len)
