edtf: value incorrectly converted in date: property

[stepps00]

London: https://spelunker.whosonfirst.org/id/101750367/

This record has an edtf:inception date of "0043~", though that date is being converted to "2043" in the date: properties. I tested an export of the record with a value of "0043?", instead, which didn't change anything.

Perhaps this is an issue with the edtf Python module, I'm not sure.

Yeah, it's a bug in the edtf library...

This is no longer an issue.. exportifying the record of London now results in:

    "date:inception_lower":"0043-01-01",
    "date:inception_upper":"0043-12-31",
