Fix a sample code snippet that assumes `absl::string_view::const_iterator` is `const char*`.  This is generally true, however in C++17 builds, absl::string_view is an alias for std::string_view and on MSVC, the std::string_view::const_iterator is an object instead of just a pointer.

Updating documentation for custom StrSplit delimiters to reflect
the fact that string_view does not have a (string_view, start, len)
constructor.
