Translations: dehumidifiers commonly have laundry and purify modes.
Some just call the purify mode fan-only, but since dehumidifiers tend
to have filters, they work as purifiers in this mode.
This partially reverts some changes from 2023.6.0, where humidifiers
were changed to use common modes as much as possible, so many laundry
modes got changed to boost. In some cases, this had a knock on
effect, as boost should have replaced high, but normal was used, with
comfort being used where normal should be.
