Summary description: Unicode bidi algorithm implementation for various LuaTeX formats

Announcement text: ----------------------------------------------------------------------

There was some extensive work for this version.

* Support for directional isolates was added

* The implementation now passes all the tests in [BidiTest.txt](https://www.unicode.org/Public/UCD/latest/ucd/BidiTest.txt) and [BidiCharacterTest.txt](https://www.unicode.org/Public/UCD/latest/ucd/BidiCharacterTest.txt)

* There are now functions which operates on Lua strings, not just nodes

* The Lua and TeX APIs were extended

* The core Lua module can be used in plain Lua as well

The API can be considered stable now.

The code has diverged from the original ConTeXt implementation due to the extensive changes and additions made in this version.
