[DS18B20] Feature Request: Trigger temperature conversion on all devices (BSP-348)

[CJCombrink]

When working with more than one DS18B20 temperature sensors, three in my case, it would be nice to call ds18b20_trigger_temperature_conversion() on all three and then only delay for the required amount before reading the temperatures from all three.

The current implementation forces me to wait x ms for each sensor where ideally I could only wait once.

I would imagine an function defined as follow:

esp_err_t ds18b20_trigger_temperature_conversions(const ds18b20_device_handle_t *ds18b20, uint8_t ds18b20_size );
