Subject: [PATCH] Fix -Wdeprecated-copy

```
boost/circular_buffer/include/boost/circular_buffer/details.hpp:263:15: error: definition of implicit copy constructor for 'iterator<boost::circular_buffer<bool>, boost::cb_details::const_traits<std::allocator<bool>>>' is deprecated because it has a user-declared copy assignment operator [-Werror,-Wdeprecated-copy]
    iterator& operator=(const iterator&) = default;
              ^
```
