feat(asset.provider): Now the DataType sent to the driver depends on …
…the DataType of the channel and theDataType of the scaleOffsetDataType field and a new ScaleOffsetDataType, LONG, has been added (#5432) * Now a dependent datatype is forwarded to the driver * fixed test * Added test for ChannelRecordHelper * Added test for dynamic valuetype * little code cleanup * Fixed bug on Long scale/offset * Fixed wrong import (cherry picked from commit bda665c)
