update reset

i was able to reproduce #3. also saw the same behavior that it **_did_** work with other boards (esp32-s3 tft feather and rp2040 feather). i think that the reset() function was raising the error because the DAC was resetting before the command was being acknowledged over I2C (this is noted in the [arduino driver](https://github.com/adafruit/Adafruit_AD569x/blob/6e725d0efbe4010b3971d011c6df82f64d6b0541/Adafruit_AD569x.cpp#L189)). i updated the function to not raise
