How to use the @xviz/parser.unpackEnvelope function in @xviz/parser

tape('unpackEnvelope name parsing', t => {
  const notype = unpackEnvelope({type: 'foo', data: {a: 42}});
  t.equals(notype.namespace, 'foo');
  t.equals(notype.type, '');

  const empty = unpackEnvelope({type: '', data: {a: 42}});
  t.equals(empty.namespace, '');
  t.equals(empty.type, '');

  const nonXVIZ = unpackEnvelope({type: 'foo/bar', data: {a: 42}});
  t.equals(nonXVIZ.namespace, 'foo');
  t.equals(nonXVIZ.type, 'bar');

  const leadingSlash = unpackEnvelope({type: '/foo/bar', data: {a: 42}});
  t.equals(leadingSlash.namespace, '');
  t.equals(leadingSlash.type, 'foo/bar');

  t.end();
