Break up volume tasks into individual image sub-tasks

[saltymouse]

Problem

If I save a volume from Craft → Settings → Assets, this triggers an ImageOptimize rebuild task (yay). However, it looks like there is a single task for the whole volume, with only a single TTR. With asset volumes containing many (and large) images, this volume's task TTR is often exceeded, failing the task and leaving the images unprocessed.

Solution

Is it possible to break up a volume optimize task into sub-tasks per image contained in the volume?

Describe alternatives you have considered

Increasing Craft's queue TTR to 10-15m still isn't enough for more voluminous volumes.
Running php craft image-optimize/optimize/create from the CLI works without timing out, but not accessible to non-terminal users.

Additional context

Craft 3.6.11.2 • PHP 8.0.3 • ImageOptimize 1.6.30 • AsyncQueue 2.2.0
