Oversampling input

Oversampling, a.k.a. supersampling, refers to fetching more samples than you strictly need for a purpose, but can use for other reasons.

For example, you might want 10 temperature samples per second, but actually sample 1000 times per second and average every 100, to get a slightly stabler output value.

This is useful for a few different but related reasons.

Avoid aliasing, and/or easier input filtering

Imitate higher resolution, and lower noise
