[feature request] "How long to read" function

[linux-lukas]

I wish there was another function that shows how long the blog post takes to read on average, depending on the post length.

This may be something that Hugo or a plugin can do. If you find a solution, feel free to submit a PR! 🙂

I'll have a look through the Hugo Docs and see how I can help. :)
