virtual_list update removed selection functionality

[bitfehler]

Hi there! Thanks a lot for this amazing library. I have been trying to build an app while following the floem main branch, which, I understand, bears certain risks. I was able to deal with all changes so far, but #760 did remove a lot of functionality from the virtual_list widget (note: I do not doubt it also brought many improvements 😉 ), such as the selection API (selection(), .on_select() etc.).

The commit and PR are unfortunately a bit sparse on details and motivation, so I just wanted to inquire if the intention is to bring this back for the next release? Or did I maybe just not manage to find out how this functionality is provided differently now?

Thanks again!

Whoops. Removing those was an accident. I'll get those added back
