This fork of the astra API has a few fixes

• Fixes C++11/14 compiling problems
• Removes the lisp preprocessor step from the build pipeline. Clisp hasn't been updated since 2010 and it was removed from most debian based distros in 2014
  • Compiling clisp is extremely difficult and it doesn't do anything for regular users of the API
