[Enhancement]: Embed Metadata - Update chapters only

Type of Enhancement

Server Backend

Describe the Feature/Enhancement

Please add an option to update only chapter metadata.

I use beets-audible to tag my M4Bs. But I've got a couple that don't have good chapter names, so I've used ABS to pull updated names and then embedded metadata. But I noticed that it wipes out some fields that beets-audible generated. I looked at Tone briefly and to my understanding it has a way to just update the chapters and not everything already. I think if you ran tone with ChptFmtNative as the only tagger it shouldn't touch the rest of the tags?

Here is the ffprobe metadata before Tone updated. I did a tone dump first, but noticed it didn't display some of the fields.

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'pre.m4b':

Why would this be helpful?

This will preserve the tags that have been established outside of ABS.

Not explicitly related to this issue. It took tone about 5 minutes to update the metadata on this file. When I'm using beets it is much faster. I'm guessing ABS is making a temp file somewhere when updating the file. Some of my system lives on a not super fast SD card and my guess is that the temporary directory might be on there. I'm using a docker install and could map the temporary directory to somewhere fast if that is possible. Which directory should I check into?
