imports using "at" are not resolved

[apb2006]

Only treated as error when processor set e.g.

var file = "test/queries/rbtree.xq/map.xq";
const opts = {
    processor: 'basex'
    , styleCheck: false
};
var linter = new XQLint(fs.readFileSync(baseUri + file, 'utf-8'),opts);
var markers = linter.getMarkers();
console.log(markers[0]);

[apb2006]

fixed in 0.3.3
