External data connection

I'm trying to load external data with ClosedXML (lastest build), but can't seem to figure out how..
The Connection Class appears to be missing, maybe it was handled differently?

I wish to load for instance a TXT file into an existing/new worksheet, doing a TextToColumns on the way (same as Excel 2016 does), or a ODATA connection..

Start by reviewing ClosedXML's current support for external data connections and the referenced Open XML Spreadsheet.Connection documentation. Clarify whether TXT import with TextToColumns and OData connections are in scope; done should be defined by agreed behavior and coverage for the requested scenarios.
