Supermarkets suppliers package their products

[BalthazarArgall]

Summary

None

Purpose of change

Apparently a lot of stuff is not correctly packaged in the supermarket, unacceptable.

Describe the solution

1. Pharmacy shelves now use the vitamin shop group instead of the off the counter drug group which could spawn morphine.
2. Pet food can now spawn as packages of kibble of different sizes and even six packs of wet food.
3. Most breads have been packaged, atm it's lots of small bread in single bags but in the future we should have big individual breads in individual bags.
4. Raw ground coffee is now found in cans/packs/boxes of different sizes and beans too.
5. Removed a ton of default containers, yay.
6. Packaged eggs properly in boxes of 6 and 12.
7. Added a 6 egg box.

Describe alternatives you've considered

1. Bird food packaging. Later.
2. Pretty sure beans shouldn't spawn in small coffee containers. A bit tired to rework that group once again, later.
3. 10 kg dry pet food is contained in garbage bags. We don't have a "big plastic bag" so garbage bag it is, I'll look into adding a bigger one in some other PR, I'm mentioning it here so people know that I know that dry pet food shouldn't spawn in garbage bags.

Testing

Spawned a lot of groups while I was making them, maybe I forgot one if I'm completely honest. At least it loads fine.

Additional context

Ignore the messy commit history.
