Not to worry! The INA219 has a built-in sample averaging mechanism.
You can ask it to take up to 128 samples and average them to produce one
number to receive over the I2C bus.

That won't be of much help as you need the average over the squared
samples, not the average over the samples themselves.

The way to do this properly, as in how a real DMM does it, is to use a
dual-slope converter that will produce a useful number with every sample.
These successive approximation converters that are common as dirt these
days are just not very good at the job of converting a signal and
producing a useful number.
