Update to survivor harness "pocket" weight capacity

Summary

SUMMARY: Content "Update to survivor harness 'pocket' weight capacity"

Purpose of change

Update the survivor harness pocket volume for new nested inventory system, initial given weight capacity doesn't allow use with any rifle despite it being the purpose of the clothing.

Describe the solution

Weight capacity for this makes no sense, as it cannot hold the items it's intended to hold. Review of many similar devices (tactical harnesses, clips, etc.), indicates they mostly handle rifles up to and around AR-15s. Current game weight of AR-15 is 7.72 kg, versus harnesses capacity of 2.0 kg. Suggest additional weight of optics and such, and that other similarly sized weapons should fit, but not long rifles like sniper rifles. Propose 8.20 kg capacity as given in commit.

Most similar devices are made of nylon and like materials. However, survivor harness leather should be easily capable of the same weights. Encumbrance should be examined and is being corrected separately by someone else. It may also be worth reviewing max volume, though some rifles may have incorrect high volumes.

Edit: After discussion in comments, updated volume to 8 L to meet modern rifle volumes included in game.

You can bump the max volume up too, the back holster has 9L/10kg pocket limits

I'm not sure of a good suggestion for volume at the moment, but I'd think double would be fine based on the guns, though most guns aren't actually that big in the item browser. Any suggestion?

I haven't gotten to a lot of longguns yet, the FS2000 is 7986ml(#36838) irl so it's not unreasonable.
