Currently each channel is updated when it is set:

mcp4728.channel_a.value = 100
mcp4728.channel_b.value = 75
mcp4728.channel_c.value = 50
mcp4728.channel_d.value = 25

via this line: https://github.com/adafruit/Adafruit_CircuitPython_MCP4728/blob/d907e3e0baa15cd50cc647d80261dac77aeb68fe/adafruit_mcp4728.py#L347

Add capability and example to allow multiple channel values to be updated synchronously.

Maybe something similar to auto_write in NeoPixel/Dotstar usage?

This might be something we want to add to CircuitPython APIs and standardize for drivers.
