Added hiking pants

Summary

Content "Adds hiking pants."

Purpose of change

I felt this was a lacking item in terms of the current pants offered, especially with the other hiking/outdoor gear. Also, I’ve been meaning to contribute to the game for awhile, and this seemed like a good place to start so I can work on larger changes in the future.

Describe the solution

I based the stats off of existing cargo pants, making them have slightly less encumbrance, less pockets, waterproof and made of synthetic fabric. They are a relatively rare spawn in normal clothing groups, and can also be found in hunting supply stores.

Describe alternatives you've considered

Not adding this item.
Also many hiking pants are convertible into shorts, but this feature is also not seen on a large percentage of these types of pants, and so it didn't feel like a necessary feature. Also potentially making it craftable, however as many pants such as work pants and army pants are not, that didn't seem like a necessity.

Testing

Spawned it in game, stats were as expected. Tested repairing it. Checked hunting supply stores, and verified that it spawned after checking a few.
