Ability to use local table.json when @base is set

[AlasdairGray]

When @base is set in the .json metadata file, you cannot use a local table.json file since csv2rdf attempts to resolve the location of the tableSchema property based on the @base value.

If we include the table definitions directly within the .csv-metadata.json file, then running the following command generates the desired output.

csv2rdf -u age.csv-metadata.json -o age.ttl -t age.csv -m annotated

If instead we try to reference a local table.json file in the tableSchema property, then running the following command generates an error as csv2rdf attempts to resolve the location of the generated URL.

csv2rdf -u age-table.json.csv-metadata.json -o age.ttl -t age.csv -m annotated

The zip file includes the csv file and the different configuration files:
age-example.zip

[AlasdairGray]

The -t flag allows us to pass a local csv file. Could a similar approach be adopted for the table.json files?

@RickMoynihan has suggested that this would need to point to a directory in which one or more table.json files exist.
