1D arrays of floats as entries for field "value" in table "signal"
Some online sensors produce multivariate measurements simultaneously. Each such multivariate measurement consists of an array of floats with fixed length. Rather than saving each element in these arrays with a unique variable_id, it could be helpful to also be able to save each array as a single entry for "value". To handle this, it is likely best to specify the expected format for "value" with the variable table, e.g. by adding a field "format" in the variable table.
Example: Most sensors produce scalar value (0D), e.g. 1 temperature value at a time. Other sensors, like spectral sensors, produce a 1D array of floats at a regular interval. For the WHDP case, this 1D case is relevant.
