flora_europaea: Check species status (native/exotic) in Flora Europaea

Description

This function check the status (native or exotic) of a species in each of the eu countries.

For that end, it checks Flora Europaea (http://rbg-web2.rbge.org.uk/FE/fe.html) and scrapes the data from there.

Note that the webpage contains more information.

As expected, the function is as good as the database is. I think for native species is robust but new exotic species are not added as to my knowledge the database is not updated anymore. The database is not able to recognize species synonyms.

See http://rbg-web2.rbge.org.uk/FE/data/countries for explanation of the database codes.
