This would "fix" the exported xml from having "22" in the embedded texture's format block.
In before this 22 prevents the xml file from importing into blender via Sollumz, caused the common error "KeyError:22" when some people editing weird-making mods.
`ShaderGroup.ShaderGroupBlocksSize` (aka `Unknown_30h`) contains the byte size divided by 16 of the ShaderGroup block and its children blocks, when they are packed contiguously in the resource file.
`DrawableBase.DrawableModelsBlocksSize` (aka `Unknown_9Ah`) is similar but with the size of the `DrawableModelsBlock`.
Incorrect values can cause crashes when the model is unloaded.
