Compile warning with clang

[alekseyt]

This is not a big deal, i'm not aware of any issues caused by this warning, but i thought i'll ask anyway:

.../include/jsoncons/sink.hpp:265:17: warning: explicitly
      defaulted move assignment operator is implicitly deleted
      [-Wdefaulted-function-deleted]
    bytes_sink& operator=(bytes_sink&&) = default;
                ^
.../include/jsoncons/sink.hpp:252:18: note: move assignment
      operator of 'bytes_sink' is implicitly deleted because field 's_' is of
      reference type 'jsoncons::bytes_sink::output_type &' (aka 'vector<unsigned
      char> &')
    output_type& s_;
                 ^

This warning appears when cross-compiling for OSX with clang 8. I'm using jsoncons 0.144.0

Thanks for reporting this. Fixed on master.

I've updated jsoncons from master and it compiles without any warnings. Thank you very much.
