Prevent deadlock when acting on parameter changes

[github-actions]

This is an automatic cherry-pick of dab9c5f1714afb45f022751584c18ba28cb88ae1

The original PR was #176 with message:

When there are multiple AXParameter callbacks in a queue, such as during the first parameter change after installation, any parameter usage, even outside a callback, will cause a 20 second deadlock per queued callback.

The workaround is to delay the call back to g_main_loop_quit() by 1 second using a timer callback.
