Fixes OSError on Windows environments

Previous behavior causes tests using this plugin to fail on Windows environments because files were still open at the time the test cleanup was trying to remove them.

This properly scopes file touches so this conflict no longer occurs. Tested on Mac [manual], Linux [Travis], and Windows [manual]

Remove runtime installation of chromedriver

This plugin no longer assumes it has permission to install drivers at runtime, and requires consumers to ensure the proper configuration.

Replace Chrome as default webdriver; refine and prune dependencies; use tox for build and testing

Dependency Changes

• Removes dependency on node and the PhantomJS package
• Adds dependency on pydantic for nicer modeling
• Adds dependency on tox

Packaging Changes

Disabling of the broken test suite represents technical debt that can be relieved down the road.
