Add a new Unconfusable Latin table (#1981)

Browse source 
This new table has just been approved by ICANN. It is the same as our existing
Extended Latin table, except with the removal of some lesser-used characters
with diacritic marks that are confusable variants.

The filenames for the IDN tables are made explicit to improve code readability.

And this reverses the removal of G with stroke from the existing Extended Latin
table (see PR #1938), so that that table continues to accurately reflect the
state of our previously launched TLDs.

This is the full list of removed characters:

U+00E1                         # LATIN SMALL LETTER A WITH ACUTE
U+0101                         # LATIN SMALL LETTER A WITH MACRON
U+01CE                         # LATIN SMALL LETTER A WITH CARON
