Add pages to trellis panels display option

Wafers always come from lots, and users want to see a display of all of the wafers in a specific lot without mixing in other wafers. The trellis is always configured to use panels (trellis by X/Y has no meaning), but users cannot control the pages. The request is to add a Pages option to the panels config, so that the user could assign the lot number to the page option. They would then be able to click next/next in the scroll bar and see a gallery of all wafers from one lot on one page, and not have any wafers from another lot shown on the same page. It’s OK if the number of wafers spills over to the next page, but generally it won’t because lots typically have a max of 25 wafers, and this fits comfortably on a page. Of course if they want to see and scroll quickly through all, they could choose not to use the page option.
