Feature proposal: Write oemof.tabular version into metadata in `infer_metadata`

[jnnr]

This will allow tracking compatibility between data and code.

Include something like this in infer_metadata:

p.descriptor["tabular-version"] = oemof.tabular.__version__

And check the version against a list of supported versions when calling deserialize_energysystem.

Done in #79
