feat: option to do indexing without a query

[iynaix]

Is there a way to run rclip without a query, just to update the index? Use case would be to have it run as a cron job so when a query needs to be run, there wouldn't be any waiting for indexing.

@iynaix, at the moment, there is no such option. I'll give it a closer look. You can always run rclip with a query and ignore the querying output. Since querying is quick, it shouldn't introduce any overhead.
