The API's classification of a current water level (stateMnwMhw, stateNswHsw), as
documented upstream:
low — at or below MNW (stateMnwMhw only);
normal — between MNW and MHW, or between 0 and HSW;
high — at or above MHW, or HSW;
unknown — the series has no MNW/MHW (or HSW) mark to compare with;
commented — gauge malfunction or disruption ("Fehlfunktion oder Störung"): the
value may be wrong; the reason is in the series' comment (TimeseriesInfo.comment);
out-dated — the reading is older than 25 hours.
Typed open (string & {}) so a value the API adds later still type-checks.
