Pysolarmanv5

Fixed

- MAJOR VERSION BUMP - v3.0.0

v2.5.0 inadvertently introduced a breaking change and has been withdrawn.

The breakage was introduced by [GH PR 33](https://github.com/jmccrohan/pysolarmanv5/pull/33)
which moves the PySolarmanV5 socket communications to a worker thread. While
this is a major improvement over the previous method, it requires that the
disconnect() method is called to close the socket.

Prior to this, the socket was implicitly closed when the PySolarmanV5 object
was deferenced. Many dependent applications re-instantiate a new object for
each poll. These applications will need to either remain on v2.4.0, or
upgrade to v3.0.0 and ensure disconnect() is called to close the connection
cleanly.

Many thanks to connesha for highlighting this breaking change in [GH issue 39](https://github.com/jmccrohan/pysolarmanv5/issues/39)
