Make compatible with sanitizers-cmake

This pull requests makes wise_enum compatible with [sanitizers-cmake](https://github.com/arsenm/sanitizers-cmake) by setting the language to C++ in the CMake project definition.

Without this wise_enum can't be used in projects that use sanitizers-cmake, because it needs to know the language of the project.

Add example file for C++11

Update readme with new improvements

Improve code readability, simplify API:

 - Instead of an array of pair, use a simple struct with named fields value
   and name
 - With improved readability from this, having two arrays no longer necessary
 - Use the term "name" instead of "descriptor" throughout documentation

Major changes to implementation strategy:

 - Rather than generating nearly everything, use much more minimal generation
   to provide a generic loop, and use those constructs from a single variadic
   macro implementation. This massively reduces the size of the codegen file,
   also allowing a far more generous number of max enums by default
 - Change approach to separating (identifier, initializer) enumeration
   arguments so that unparenthesized commas in initializer are no longer an
   issue
 - Change documentation to match
