When using fpp as part of a pipeline you don't want it to fall back to reusing the previous result. See [src/processInput.py#L60](https://github.com/facebook/PathPicker/blob/3d4d8b064eec228ef3950d8c8e5b3287bbe9a987/src/processInput.py#L60) Would a PR introducing a flag disabling this option potentially be accepted?
