State pattern for enocean:cumulativeValue

[diRk262]

The receivingEEPId: A5_12_03 and channelTypeUID: enocean:cumulativeValue Logs the following warning:

[WARN ] [se.internal.SseItemStatesEventBuilder] - Exception while formatting value ‘16.9 ㎥’ of item Wasser_gesamt with format ‘%d %unit%’: d != java.math.BigDecimal

Currently the state pattern is defined as %d %unit% . However it should be defined as %.1f %unit%.
The currentFlow channel should have the same problem.

Looks like this is also the case for channel linked to a Weatherstation (Multisensor).
