/*
* Taken from renderer/app/helpers/temp.js with minor cosmetic changes.
* Promisify the temp package. The temp package provides a 'track' feature
* that automatically cleans up temp files at process exit, but that is not
* very useful. They also provide a method to trigger cleanup, but that is not
* safe for concurrent use. So, we use a disposer to unlink the file.
