Describe the question

I have a remote mountpoint. So.. The internet condition isn't that good, in Yazi, it will run mime fetcher on lots of files in batch, consuming unneeded IO and data.

Now if totally disabling the mime fetcher, files won't open - yazi needs to know the mime type first then decides how to open the file, but I disabled it and yazi is unable to do it at all.

In this case, it will be good if yazi has mime fetcher on-demand, i.e. only fetches the file mime type when I try to open a file, or I can just manually run the fetcher on a file.

Anything else?
