Add Bidi mirroring data for Unicode 3.0.1 through 4.0.1

Unicode published BidiMirroring files from 3.0.1 on, but the resources
only included them from 4.1.0. Unicode 3.1.0, 3.1.1, and 4.0.1 did not
update the file, so they reuse the previous release's version.

The 3.2 and 4.0 files map U+2A2D to U+2A2C, which itself maps to U+2A2B.
The writer assumed every mapping had a matching reverse mapping, so it
would have dropped both one-way mappings in that chain. It now emits
those mappings separately; output for symmetric data is unchanged.

+# BidiMirroring-1.txt
+# 
+# This file is an informative supplement to the UnicodeData file. It
+# lists characters that have the mirrored property
+# where there is another Unicode character that typically has a glyph
+# that is the mirror image of the original character's glyph.
+# The repertoire covered by the file is Unicode 3.0.1.
+# 
+# The file contains a list of lines with mappings from one code point
+# to another one for character-based mirroring.
+# Note that for "real" mirroring, a rendering engine needs to select
+# appropriate alternative glyphs, and that many Unicode characters do not
+# have a mirror-image Unicode character.
+# 
+# Each mapping line contains two fields, separated by a semicolon (';').
+# Each of the two fields contains a code point represented as a
+# variable-length hexadecimal value with 4 to 6 digits.
+# A comment indicates where the characters are "BEST FIT" mirroring.
+# 
+# Code points with the "mirrored" property but no appropriate mirrors are
+# listed as comments at the end of the file.
+# 
+# For information on bidi mirroring, see UTR #21: Bidirectional Algorithm,
+# at http://www.unicode.org/unicode/reports/tr9/
+# 
+# Please address any comments to <errata@unicode.org>.
+# Note that this is an archival address: messages will be checked,
+# but do not expect an immediate response.
