Add support for CiA 311 XML Device Configuration

[juliusz-t]

It would be nice to add support for the CiA 311 XML device description. Currently, library supports parsing EDS, DCF, and EPF files via canopen.objectdictionary.import_od() and canopen.network.Network.add_node(). Attempting to load an .xdc file results in a NotImplementedError.

The XML device description is mandatory for CANopen FD devices, so it's a possible prerequisite for #449.
Unfortunately the format specification is hidden behind the member wall. :/

Are there any other open source implementations that already implement the format? I don't have access to the (non-public) specs either. The feature would definitely be welcome and fit in nicely (with an adequate implementation). But I don't see a way to implement it without having some kind of format description available. Whoever gets access to it is welcome to contribute an implementation here.

I checked and found that this document is very old. But maybe there is no newer version.

There is a newer document CiA 1311, relating directly to the FD standard. I think both are still relevant though.

Ok thanks.I found.
