KeyError: 'Z8'

[TimRepke]

It seems like WoS recently changed their export format:

    if has_item_per_line[heading]:  # Iterable field with one item per line
       ~~~~~~~~~~~~~~~~~^^^^^^^^^
KeyError: 'Z8'

Based on the table at the bottom of this page: https://webofscience.help.clarivate.com/en-us/Content/export-records.htm (already mentioned in #14)

I automatically added all missing entries to the tags.py:

Please note, that the "splittable" and "one item per line" settings are not verified. I just thought I'd share this outside a PR in case anyone wants to pick this up and properly incorporate it.

There are even more tags now that are not even documented.

    # Undocumented tags
    ("ZS", "Magic undocumented tag", False, False),
    ("ZB", "Magic undocumented tag", False, False),
    ("ZR", "Magic undocumented tag", False, False),
    ("ZA", "Magic undocumented tag", False, False),
    ("ER", "Magic undocumented tag", False, False),
    ("EF", "Magic undocumented tag", False, False),
    ("G1", "Magic undocumented tag", False, False),

Thanks for the report! I'll try to figure out what those tags represent in the coming days.
