Add option to disable automatic undiscard when clicked on a tab

[rudolphos]

Can this be added? Similar how it was in TGS extension, it's way faster and less memory-consuming to move through discarded tabs before unsuspending them than to unsuspend one after another and cause high memory issues.

Should probably resolve this in favor of https://github.com/rNeomy/auto-tab-discard/issues/41
