This commit performs both lossless and lossy compression on every .obj and .png in homedecor. The .png files were all 100% losslessly compressed using ect.exe and optipng.exe (more details below) at maximum settings. The .obj files were lossy-compressed so that comments were removed, trailing 000's were removed and all numbers rounded to 3 decimal places max. Blender exports at 6 decimal places but for minetest, 3 decimal places is the absolute maximum a person with anything under a 256K screen will ever need.

## Results
Original entire modpack size: 6343.5 KB
New entire modpack size:      5312.2 KB
Total Reduction:              1031.3 KB  (16.3% less)
Please note that actual media size is likely more like 4,500 KB so media reduction is more around 20-25%.

## Details / What actions were actually performed

Used these programs:




Ran this command on every .obj: (fast)

luajit.exe compress.lua -f <file> -precision 3

Ran these commands on every .png: (slow)
ect.exe  -9 -strip --allfilters-b <file>
optipng.exe -o7 -strip all -clobber <file>

Note that for future compression, I recommend only using optipng.exe instead of both. ECT can get better results but it takes a LOT longer and only ever saves another 1-2% of the file size. Not worth an extra 10-20 seconds per texture file in my opinion.
