WalkthroughThe documentation for the BH1750 Ambient Light Sensor has been updated to include a new section on I²C configuration when using higher frequencies. This section emphasizes the importance of a timeout option in the I²C configuration at frequencies above 50-100kHz, detailing the differences in default timeouts between the Arduino and IDF frameworks. An example configuration for operating at 800kHz is also provided, including a timeout adjustment. Changes

53-62: Consider adding context for the timeout valueWhile the example configuration is correct, it would be helpful to explain why 10ms was chosen as the timeout value. This would help users understand if they need to adjust this value for their specific setup.
Consider adding a note explaining:
- Why 10ms is a suitable timeout value
- What factors might influence the need for a different timeout value
- Any potential trade-offs of using a longer timeout
