• Bug fix
• Feature
• Documentation update

Description

Celluloid is a popular MPV frontend. Since celluloid can pass mpv arguments by using a 'mpv-' prefix in the command args, I figured it'd be easy to add. It just uses mpv on the backend after all.

I opted for not adding a new case in the switch, but instead adding the "celluloid" pattern in the mpv option. I then added an optional prefix, which is set if the player is celluloid. It could be done as a seperate option, but I wanted to prevent duplicate code.

I bumped the version to 4.10.0 as I noticed that is what you guys were aiming for in the next release. I checked 'range selection' as working, as you guys are already aware of the pre-existing bug with range selection and it's not related to this PR. The readme and help still mention that --skip only works with mpv, but since celluloid is still just mpv, I thought it was still correct.

Note: To make this work the user would have to copy ani-skip's skip.lua to the scripts folder under ~/.config/celluloid/scripts/ instead of ~/.config/mpv/scripts/.

Thanks for the dettailed explanation and thoughtful implementation.
I'd like to see the readme and the manpage updated to reflect the new capability.
Also please iron out that one shellcheck complaint you seem to have missed.

Then I'll test it myself too, and see if it works. Merging may have to wait until 4.10 is merged too, but maybe we can include the feature in the release.

Thanks for the quick reply.
I added the capabilities to the README, help and manpage, as well as a small note to the README's ani-skip section to explain how to get ani-skip to work with celluloid. Let me know if you need me to make any other adjustments.
