Feature request: luci-app-attendedsysupgrade: add config options to automatically de-select packages

What would you like to see in luci?

i'm running a OpenWrt router with several 3rd party packages. everytime I do attended sysupgrade, all manually installed 3rd party packages should be de-selected from the list. this is somehow tedious to do manually.

if any 3rd party package is not deselected and slip into the ASU build request, the build will fail and i have to start all over again.

so i hope there will be a config option, which takes a list of packages, and automatically de-select them before the request is sent to the ASU.
