fix setLED to allow for more than 63 TLC59711 devices

[s-light]

• Arduino board: Adafruit ESP32-S3 Reverse TFT Feather

• Arduino IDE version (found in Arduino -> About Arduino menu):

Version: 2.2.1
Date: 2023-08-31T14:16:33.536Z
CLI Version: 0.34.0
core esp23: 3.0.0-alpha

• List the steps to reproduce the problem below:
  use more than 63 TLC59711 devices.

currently the library has a datatype that is to small to handle more than 255 LEDS.
each TLC59711 has 4 LEDs: so max 63 are supported currently.

i have much more TLCs

(if i remember correctly about 168 TLCs)

it is a simple fix.
i will prepare a pr.
