4b89da9463 lib/decimal: rename significant decimal digits to significant figures (#698)

applied to all significant figures, not just decimal ones.

5d439cc6f2 lib/{decimal,encoding}: optimize float64<->decimal conversion for arrays with zeros or ones
Time series with only zeros or ones frequently occur in monitoring, so it is worth optimizing their handling.
