Uruguayan eID: note that both applet versions share the biographic layout

[carlosplanchon]

Follow-up to #1, now with a v5 card in the picture. @nicolasgutierrezdev ran the
same structural read on a v5, which is hardware I do not have, so the comparison
below covers both applet generations rather than just the v4.

Both cards give the same ten tags, 1F 01 to 1F 0A, in the same order, with
1F 08 four bytes wide on both. So the biographic layout did not change between
applet generations, and nothing in that section is specific to one of them.
Worth stating on the page, since the card capabilities above do distinguish the
two versions.

The surname warning also gets firmer. Both cards came with 1F 02 zero-length
and both surnames packed into 1F 01, so the text now says that instead of
leaving it as something seen on unspecified cards. Two cards is still two cards,
and the wording keeps the sample visible rather than claiming it always happens.

One thing that looked like a finding and was not: on one of the cards 1F 01
came through with no bytes above 0x7F, which would suggest the card strips
accents from surnames. It does not. That surname is registered without an accent
in the civil registry, so the field is a faithful copy. Nothing to document, but
worth knowing it was checked.

No personal data was read for any of this, only tag numbers, field lengths and
encodings.
