Fixes:

• Fixed streamed assets from Modern Warfare 2019/Black Ops Cold War not exporting
• Fixed invalid strings in Modern Warfare 2019

QOL:

• Added Black Ops Cold War's 'roughness map' semantic to the table as 'glossMap'*

* Note: these are not gloss maps, this is mostly done for FlickyTuts who requested it, but keep in mind they are roughness maps
