INTERLIS Export with labels failing

[sjib]

Exporting the test-dataset-DSS gives the following error (With all 3 datamodels):

`Ein Fehler trat bei der Ausführung von Python-Code auf:

See also my review in #23, can be fixed by defining export_label_positions() here

@sjib how should look the t_ili_tid for labels in the xtf? Should I use the function tww_sys.generate_oid?

@cymed Any preferences for AG64/96 compatibility?

[cymed]

I prefer t_id = t_ili_tid = obj_id on export. generate_oid is the most straightforward solution.

If we use generate_oid, we need to reset the sequence after export, otherwise we cap 1M too quickly. Automated exports are usually on a weekly basis, with i.e. 25k labels would cap after 40 weeks.
