Support IO expander used in the SparkFun breakout board with latch terminals https://www.sparkfun.com/products/17047 17047-SparkFun_Qwiic_GPIO-04

Arduino Library https://github.com/sparkfun/SparkFun_Qwiic_GPIO_Library

Datasheet https://www.ti.com/lit/ds/symlink/tca9534.pdf

identical except with internal pullups;

https://www.ti.com/lit/ds/symlink/tca9554.pdf I'm hoping to swap the chip on one of these boards to this one if it gets supported for an alarm panel replacement.

Do you know if this is going to be added? I've purchased a esp32-s3-korvo-2 v3.0 along with the ESP32-S3-Korvo-2-LCD V1.0 and it uses the TCA9554 with the i2c address of: I2C Address： 0'b 0100 000x
