should use broccoli-persistent-filter

https://github.com/rickharrison/broccoli-asset-rewrite/blob/master/index.js#L1

without this, this will cause extra FS invalidations, causing issues described here: https://github.com/ember-cli/ember-cli/issues/5485

If you have questions, don't hesitate to reach out.

Start with index.js at the linked line and inspect how the plugin currently watches and rewrites the source tree. Read the broccoli-persistent-filter documentation and compare its invalidation behavior with this plugin. Done means the plugin uses it and no longer causes the extra filesystem invalidations described in ember-cli/ember-cli#5485.
