do not compile

Arduino-HomeKit-ESP8266-master/examples/legacy/simple_led/simple_led_accessory.c: In function 'led_update':
simple_led_accessory.c:67:13: error: 'PWMRANGE' undeclared (first use in this function)
67 | int pwm = PWMRANGE - (int) (led_bri * 1.0 * PWMRANGE / 100.0 + 0.5f);

This issue has nothing to do with this project. However, I decided to try redefining the PWMRANGE variable.
I just added a declaration int PWMRANGE = 1023; to the method led_update()
