SortedRecordingConverter for solving unit electrode provenance in sorted data

[h-mayorquin]

This has #1124 as a base and should be done after that.

This converter can be used to write sorted data and keep the correct electrode provenance of the units (display electrodes in the units table). The converted takes care of handling the correct map between units and electrodes which is important for multiple recording/probes such as the one discussed in #1112.

#961
