Version 2.0.0

* `picobox.push()` can now be used as a regular function as well, not only
   as a context manager. This is a breaking change because from now one a box
   is pushed on stack immediately when calling `picobox.push()`, no need to
   wait for `__enter__()` to be called.

* New `picobox.pop()` function, that pops the box from the top of the stack.

* Fixed a potential race condition on concurrent calls to `picobox.push()`
  that may occur in non-CPython implementations.
