2-letter location codes improperly handled

[WayneCrawford]

My stations have location code '00'. The code on line 100 of io.py splits this into "0" and "0":

    for loc in sta.location:

        # Construct location name
        if loc == "--":
            tloc = ""
        else:
            tloc = copy.copy(loc)

        ...

I got around this while still allowing the break instances in the indented part to work by changing the first line to:

    for loc in [sta.location]:

but maybe there's something more subtle in play and the developer will offer another solution

Thanks for pointing this out. The handling of station codes certainly needs to be straightened out. The expected list behaviour is inherited from other codes (StDb).
