Update timezone data file to IANA 2025b

Ingested tooling from https://github.com/fmidev/smartmet-timezones and updated timezone data README so we have a means to regenerate the file that is documented. Compared to IANA 2016c, the timezone information in 2025c no longer has a distinction between short and long names. For example in 2016c America/Denver used MST for short, Mountain Standard Time for long, but America/Boise used MST for both. With 2025c they both use MST for short and long, which also means that the built-in "Coordinated Universal Time" long form is now displayed as "UTC" like the short form. While this does not fully resolve #67, it does help us maintain the time zone data file better.

+# Generic Appveyor build script for boostorg repositories
+# See: https://github.com/boostorg/boost-ci/
+#
+# Instructions for customizing this script for your library:
+#
+# 1. Customize the compilers and language levels you want.
+# 2. If you have more than include/, src/, test/, example/, examples/,
+#    benchmark/ or tools/ directories, set the environment variable DEPINST.
+#    For example if your build uses code in "bench/" and "fog/" directories:
+#      - DEPINST: --include bench --include fog
+# 3. Enable pull request builds in your boostorg/<library> account.
+#
+# That's it - the script will do everything else for you.
