Unique images for Embalm/Eternalize tokens, Squad tokens, Offspring tokens, Osgood token

**Is your feature request related to a problem? Please describe.**
Some cards that create tokens that are copies of existing cards actually have specialized token images for the copies, like Warhammer (and now Fallout) decks' Squad cards, or Osgood, Operation double. They do not, instead using the card art of the original card—even though several of these tokens (the Squad cards at the least) have data in the "token-images" file. (Which indicates that the files are actually being downloaded, but unused.)

**Describe the solution you'd like**
The Squad cards and Osgood should use the specialized token images that were created for them instead of the images of the original card. Some kind of exception might have to be coded in for the Squad ability and Osgood.

**Describe alternatives you've considered**
I can't think of an actual alternative to this that doesn't involve leaving it as-is. This would be particularly disappointing in Osgood's case, since the token artwork actually depicts a different (yet identical) character and the other half of the regular card's artwork.
