WatchInfoModel.publishedMedia can now reference resources inside Pebble Packages.icon~bw.png and icon~color.png,
but no icon.png), your build will fail. You can work around this by creating an
unused, un-tagged icon. This file will be validated, so it must be a valid icon.health_service_metric_accessible always returns false when
checking the accessibility of HealthMetricHeartRateBPM.
Instead, use
health_service_metric_aggregate_averaged_accessible(HealthMetricHeartRateBPM, time_start, time_end, HealthAggregationAvg, HealthServiceTimeScopeOnce)
