Updated binary release

This release contains a binary version of the Vale tool that supports building https://github.com/project-everest/hacl-star/tree/fstar-master/vale . The binaries are .NET executable and dll files, which run on Unix with mono ( https://www.mono-project.com/ , see https://github.com/project-everest/vale/blob/master/INSTALL.md ) or on Windows. The tool implements both Vale/Dafny and Vale/F*.

Version 0.3.11 turns the type checker on by default and adds support for quickcode invariants.
