Renamed to zend-stratigility / Zend\Stratigility

Namespaces become:

- src: `Phly\Conduit` -> `Zend\Stratigility`
- test: `PhlyTest\Conduit` -> `ZendTest\Stratigility`

All code is updated to use the new namespaces, and adds an appropriate license
block. Additionally, now uses zend-diactoros for PSR-7 implementation when
testing.
