base: Expose GHC.Unicode.unicodeVersion
This exposes a Data.Version.Version representing the version of the
Unicode database used by `base`. This should clear up some confusion I
have seen in tickets regarding with which Unicode versions a given GHC
can be expected to work.
While in town I also regenerated (but did not update) the Unicode
database with database 12.0.0. Strangely, the file cited in the README
no longer existed. Consequently, I used
https://www.unicode.org/Public/12.0.0/ucd/UnicodeData.txt and was
slightly surprised to find that there were a few changes.
