API incompatibility with Eleventy 1.0

[mraerino]

When trying this Plugin with Eleventy 1.0 I get this error:

[11ty] Problem writing Eleventy templates: (more in DEBUG output)
[11ty] > Having trouble writing template: _site/posts/hello/index.html

`TemplateWriterWriteError` was thrown
[11ty] > The "path" argument must be of type string. Received undefined

`TypeError` was thrown:

this is likely because, the function context for addTransform callbacks no longer passes outputDir: https://github.com/11ty/eleventy/blob/08fe54e03da025cda24c4b25b5b8a8d0007b4689/src/Template.js#L552-L556
consider using path.dirname(outputPath) instead.

Yeah, this hasn't been updated since v1.0 was released. Haven't had time since it was released, but will hopefully get to it soon. In the meantime, PRs are definitely welcome!
