v6.2

This release eliminates the error "DPI-1054: connection cannot be closed when open statements or LOBs exist". It also adds support for creating temporary LOBs and binding LOBs directly to a cursor. You can now also use a connection as a context manager to close the connection at the end of the block by using the new cx_Oracle.__future__ object. This will become the default and only behaviour of using a connection as a context manager unless an issue is raised requesting the original behaviour to be retained. The code was reorganised and simplified in order to streamline further maintenance and a number of bugs were fixed. See the full release notes for more information.
