Unicode Character Database files, used as test data and as the source of a generated table.

What it's for
-------------
LineBreakTest-<version>.7z holds the Unicode Consortium's conformance test for UAX #14, the Unicode Line
Breaking Algorithm (https://www.unicode.org/reports/tr14/).  Glass.UnitTests unpacks it into Junk as a prebuild
step and checks TextLayout's word wrap against it.

UCD-<version>.7z holds the property files Glass's typesetting reads:
  LineBreak.txt               line break classes
  EastAsianWidth.txt          East_Asian_Width, for UAX #14's $EastAsian
  DerivedGeneralCategory.txt  General_Category, for LB1's SA resolution, LB15a/b and LB30b, and the space
                              separators (Zs) a font lacks
  emoji-data.txt              Extended_Pictographic, for LB30b
  DerivedCoreProperties.txt   Default_Ignorable_Code_Point, drawn invisibly when a font lacks them
Scripts\GenerateUnicodeProperties.py reads them to regenerate
Modules\Glass\Glass\Typesetting\UnicodeProperties.Generated.cs, and Glass.UnitTests unpacks them into Junk to check
that table against every code point.

Stored as .7z (3rdParty\7-Zip\7zr.exe) because the plain text is ~3.1 MB and ~2.0 MB respectively, and compresses
to ~146 KB and ~158 KB.
