No `clang_getToken` binding in clang-sys

[yingmanwumen]

I am a beginner of LLVM, and writing some toy code by following C++ code.
There is a C interface in libclang named clang_getToken, and the prototype of it is

CXToken* clang_getToken(CXTranslationUnit TU, CXSourceLocation | Location);

But I didn't find the corresponding binding in clang-sys.
Is that a neglect or a deliberation? Thanks.

Missed this function by mistake.
Added in v1.3.1.
