RuntimeError: Unable to enable VEML7700 device

Running Micropython on Pi Pico and attempting to use the VEML7700 connected to a TCA9548a on Channel 0. Platform_Detector and Blinka src files are installed. Other adafruit libraries are working fine. As you can see in the output below my VEML6070 is communicating on channel 1 without issues.

```python

# Setting Sampling Frequency
sample_half_sec = time.ticks_ms()
sample_sec = time.ticks_ms()

i2c = busio.I2C(board.GP5, board.GP4, frequency=400000)
tca = adafruit_tca9548a.TCA9548A(i2c)

for channel in range(8):
if tca[channel].try_lock():
print("Channel {}:".format(channel), end="")
addresses = tca[channel].scan()
print([hex(address) for address in addresses if address != 0x70])
tca[channel].unlock()

# UV SENSOR
uv = adafruit_veml6070.VEML6070(tca[1])
# Alternative constructors with parameters

# uv = adafruit_veml6070.VEML6070(tca[1], 'VEML6070_HALF_T', True)

def UV_DATA():
uv_raw = uv.uv_raw
risk_level = uv.get_index(uv_raw)
print("Reading: {0} | Risk Level: {1}".format(uv_raw, risk_level))

# LUX SENSOR
luxsensor = adafruit_veml7700.VEML7700(tca[0])
print("Light Integration Time:", luxsensor.light_integration_time)

while True:

I've flashed the same Pico with CircuitPython and the sensor works properly with the same library.

Reproduce the failure on the Raspberry Pi Pico under MicroPython using the provided TCA9548A and VEML7700 setup. Read /lib/adafruit_veml7700.py around line 197 and compare the initialization behavior with CircuitPython. Done means the VEML7700 initializes through channel 0 without RuntimeError and produces light readings.
