Description

To better manage inclusion of VGNC species in the xref pipeline, change to VGNCParser to make it generic.

Use case

To enable better handling of running xref for vgnc.

Benefits

We dont have to maintain a separate list of species in the ini file.

Possible Drawbacks

Testing done for single parser runs for 5 VGNC species. Compared with number of xrefs from 101 runs.Number of xrefs added were > 101 runs.

If so, do the tests pass/fail?
