Adds the ability to toggle whether to use `upload_date` or `release_date` in the date_range plugin, which is used to cull older videos.
```
date_range:
type: "upload_date"
```
If using the Only Recent preset, it will be automatically applied based on whether your season/episode ordering uses release date or upload date.
