SNT957W devices: apply correct scale.

Based on logs in #1907, all values are scaled by 10, and ranges of
original PR for temperatures seem to support that.  Humidity is also
scaled by 10 in the log, so adjusted some ranges to match.

Assume both variants (with and without humidity) are the saame.

Issue #1907
