> In a scenario where there are many files which all share the same key/value types, e.g.,
when dealing with measured data from sensors, it should be possible to chain-load multiple
files. That means, there should be a reader which can be supplied with one or more directories
containing files, and it should be possible to read the records of all files in order.
