VSCode julia extension

[hros]

the julia extension of VSCode does not recognize the syntax of CBinding
The closing brace of a @cstruct raises a parse error (red wiggly line)
Additionally the @cstruct definition along with all fields are not recognized, and as such any future reference to these types in the code shows a "Missing reference" error

Enabling syntax highlighting in code editors should be realizable now for the contents of c"..." and cxx"..." blocks as it is now just standard C/C++ code embedded in the file.
