Show interesting statistics in the template page

It would be really nice to show, when clicking e.g. a template like this:

https://nft.protonchain.com/10

Besides "Edition Size" also:

• nr of minted items (sometimes the edition size is big, but the minted nr is not the maximum supply)
• nr of items for sale (this is easy: total of items in the dropdown)
• nr of items not for sale (=minted amount - amount items for sale)
• list of owners (users who hodl this but didn't put it for sale and if they have many of this, how many per user)
• total amount of sales so far (basically how many times this template has been traded)
