Sensor request: Waveshare Environment Sensor HAT for Raspberry Pi

[WirthmU]

Could you please add the sensors of the Environment Sensor HAT for Raspberry Pi (I2C Bus) which are not yet implemented (i.e. TSL25911 digital ambient light sensor; ICM20948 Motion Sensor; SGP40 VOC sensor)?

They are describe here:

Hey! Adding those sensors would require implementing I2C drivers for each (TSL25911, ICM20948, SGP40) and integrating them with indi-allsky. First, check if Linux already has drivers (i2cdetect, lsmod). If not, you'd likely need to write a custom INDI driver or convince the maintainer to add them. The project may also accept a hardware donation to test. It's a great feature request though — good luck pushing it forward!

Fortunately, Adafruit already has SGP40 and ICM20948 libraries available. I have merged #2749 which includes these sensors.

For the ICM20948, I have only implemented the magnetometer readings. Gyro and Accelerometer readings are not particularly useful for an all sky camera.

I believe the TSL25911 is the same sensor as the TSL2591 in a different form factor. The interface should be the same.
