Testing

1. Create a world with the following mods

• Disable NPC Needs
• Aftershock
• CRIT Expansion
• DinoMod
• Generic Guns
• Magiclysm

2. Test that a new game can be started in it
3. Test the amount of water that fits into a steel jerrycan stayed the same (80 units)
4. Test that 80 units of water (20L; 1 full steel jerrycan) weigh 20kg
5. Note: I did not do any testing for changes to data/legacy//.json because I don't know how to wish for legacy items
6. Test that the volume of 1000 nutriments (id: afs_calorie_pill) stayed the same (0.2L)
7. Test that the volume of 1000 CQB SI shotguns stayed the same (1 L)
8. Test that the weight and volume of Dilophosaurus stayed the same (400 L; 400 kg)
9. Test that the weight and volume of 1000 grenade belts (id: belt40mm) stayed the same (1L; 0 kg)
10. Note: I did not test some of the affected items

Additional context

This patch was brought to you by the following script:

#!/usr/bin/env bash
set -eux

echo "Using JSON formatter: ${JSON_FORMATTER:=tools/format/json_formatter.cgi}"
echo

# The data/ directory is a mess:
# 1. It has a json/ subdirectory even though there is plenty of JSON
#    outside that subdirectory.
# 2. Most JSON files in data/ have a uniform structure (see example 1 below),
#    but there are exceptions - files that have a completely different structure.
# The following command collects the names of all the files that use the uniform
# structure ignoring all files that don't. It also looks in utilities/.
# Even though utilities/ does not contain any loadable data, it contains
# examples. I want to modernize the documentation too.
#
# example 1
# [
#   {"type": "foo", ...},
#   {"type": "bar", ...}
# ]
#
mapfile -t FILES < <(
	find utilities data \
		-name '*.json' \
		-not -path 'data/raw/color_templates/no_bright_background.json' \
		-not -path 'data/names/*' \
		-not -path 'data/mods/replacements.json' \
		-not -path 'data/fontdata.json' \

# Piping game data through jq introduces some noise because jq does not
# distinguish between 123.0 and 123. I use some git rebase magic
# to work around this issue. After running this script run:
# git rebase --onto=master modernize-volume-weight-noise modernize-volume-weight-2
git checkout -b modernize-volume-weight-noise master
for F in "${FILES[@]}"; do

Once this is merged I'll create a separate PR to replace "400000 ml" with "volume": "400 L"
