v2.2.2

Update default precision on exponents to be a parameter definable in settings (ADNotations.Settings.exponentDefaultPlaces). By default, this is 3.

This precision is used when a call to .format leaves precision undefined (by e.g. not having that parameter at all), and only matters for certain notations (basically, those with an exponent). v2.2.1 behaved as if this was 3, v2.1.0-v2.2.0 inclusive behaved as if it was 0, and versions before v2.1.0 behaved as if it was 3.
