Change description

Extended the ICM42670 driver with sensor hub
Added an AHT30 driver
Added an example of sensor hub usage

---

Note

Medium Risk
Introduces new I2C bus initialization and a new BSP-level sensor API plus new sensor components, which could affect board bring-up and component packaging if misconfigured. Changes are additive and largely isolated to ESP-BOX-3 and the new sensor drivers.

Overview
Adds a new sensor hub integration path across the repo: a new components/sensors/aht30 temperature/humidity driver (with sensor-hub detect/impl hooks) and updates components/sensors/icm42670 to expose sensor-hub implementation hooks and declare a sensor_hub dependency.

Extends the esp-box-3 BSP to advertise BSP_CAPS_HUMITURE, create a new bsp_sensor_init() API, and initialize a second “dock” I2C bus so IMU (icm42670) and humiture (aht30) sensors can be instantiated via iot_sensor_create().

Adds a new examples/sensors app demonstrating polling + event callbacks for IMU and humiture sensors, and updates generated docs/README tables and CI/workflow metadata (component upload list, build-test rules, capability/feature emoji mapping) to include the new HUMITURE feature and new sensor components.

I made first fast round and left some comments.
-Do we really need public API for sensors?

• For example icm42670 doesn't need anything in header file. Same for aht30
• Can we move icm42670 into sensor/ too?
• We should add aht30 into upload_component.yml

I think that we should have public API for these sensors because they are also components all by themselves and that way we eliminate the need to use them with the sensor hub (which we use at the moment but we might switch to something else in the future).

* Can we move `icm42670` into sensor/ too?

Yeah, done.

* We should add `aht30` into `upload_component.yml`

Good point. Done.
