Display how many of this item are found by us

This can be a number over the upper right corner of the item.

We can show the exact count of the item being collected or "999+" if it's just too many.

This one is a maybe. It adds save bloat, but is kinda interesting. Needs more thought.

It shouldn't be a too big bloat.
Storage side, add another list in storage similar to "FoundItems", which when put side by side with it, can be extracted as item's count.
For itemsFound (of type List), use a new custom type to store it (of type List maybe), which contains the original Item, plus found count etc.
The same applies to the found date thing in the other issue.
