Add more Mini fold-up/folio options

From Kulapti (KQ#3584) see: https://discord.com/channels/726108551428440206/750875955219922964/1068368688236998656

I'd prefer it to be in 3-4 page sets instead of 2-3 . I haven't tried at all to figure out how to simplify the folding for that though, it might end up being a lot more trouble to cut out the pages

I read "3-4 page sets vs 2-3" as a row of 5 folios, 3 of which were one sig, 2 of which were part of another sig split across 2 rows. So still 6 rows, 3 folio each, with a tail end of 3 4-folio sigs (6/2 = 3)

Also from potatoe#4771 see: https://discord.com/channels/726108551428440206/750875955219922964/1068610944885854278

if possible it would still be nice to add the 5 page option maybe...

The split row option would be a headache (have to lay out in batches of 40 🙄 ) but still very doable
The main blocker here is re-working the UX so that Wacky selection doesn't take up over half the page (blocker for several other new impositions too, really)
