To regenerate icons

1. Have habmodules and shipbuildericons files in ./resources folder. You can find them at C:\Program Files (x86)\Steam\steamapps\common\Terra Invicta\TerraInvicta_Data\StreamingAssets\AssetBundles
2. run

   rm -rf ./public/icons/habmodules/ ./public/icons/shipbuildericons
   
   python scripts/export_unity_textures.py ./resources ./public/icons

I am currently using icons from the experimental branch, it should be working fine. If it's not then fix it (like keep two separate icons sets maybe?). For now seems excessive.
