MRC Converter suite: Enpass to 1Password - unexpectedly matched multiple outkey values for 'url'

@charliesigma

Thanks for the dump; it's always good to see the variety of data that exists.

Generally the converter suite uses labels, as this is the way it grew over time. Most password manager exports are simple label / value pair based exports (e.g. CSV files). Exports where data is typed have traditionally been rare, yet have become more common. Enpass is no exception here - its early export formats were awful. Since this particular converter still has to support older export formats, I can't just change it to assume typed data. At the stage of conversion where this needs to happen, the key / value pairs are simply being collected, to be generalized and record-split later. This is why you see the workaround to append UID values, and why some patterns in the field matching templates support those appended UIDs. But this clearly is grossly inadequate.
