Could someone a little bit more elaborated what should be done in this task?

At the moment, deequ does not support any metrics calculations on BigDecimal columns. The task here would be to integrate those. A problem ist that most of our analyzers produce a DoubleMetric (e.g. for the max), but here we would need to implement a new Metric that operates on BigDecimals (and ensures that the results are numerically sound).
