'calculateLux' unexpected overflow behavior due to use of uint16_t #41

Arduino board: ESP32
Arduino IDE version (found in Arduino -> About Arduino menu): 1.8.16
List the steps to reproduce the problem below:
In dark conditions a call to apds.calculateLux inverts values and returns values at or near 65534.
You can reproduced this via:
uint16_t lux = apds.calculateLux(r, g, b); or uint32_t lux = apds.calculateLux(r, g, b);

This is a straightforward fix and I can make a pull request if this repo is still being maintained.
