WindowsMRAsset Converter -replace-textures flag causes conversion to fail

[thmignon]

When converting an asset with the -replace-textures flag set the converter silently fails during the compression step. Removing the flag causes the same asset to convert successfully.

Does it happen with every asset you tested? If not, do you have an asset that you can share that repros?

I tried the flight helmet model from the sample repo and it ran successfully, but the model that repros is fairly large so I've uploaded it here: https://1drv.ms/u/s!Autah3UgSru0uDVOC-2PhBm8ySvP
