[IMP] stock{_picking_batch}: print sn/lots from picking

Before this commit we could print the product labels of a picking from a
picking, but we couldn't print only the lots/sns. This commit adds in
this ability. Because we want to be flexible with this label printing
(i.e. have the option to choose between printing zpl or pdf + 1 per
unit or per lot/sn), we include it in the general "Print Labels" button
with additional wizards.

Note that we assume:
1. If there are no lot_ids in the picking => default to only product
   labels wizard (i.e. this also means if a picking that only creates
   New Lots/SN, lots/sns will not be printable until picking is
   validated.)
2. Lots/SN PDF labels will only be in the 4x12 label format
3. Batch pickings can also print lot/sn labels
