Conflicting license statements in VGT

VGT seems to have the Apache 2.0 license, which states that the given code can be used for commercial purposes, but the `Readme` below states that the repo is only available for research purposes.
This is a conflicting statement, essentially making it a [crayon license](https://lists.opensource.org/pipermail/license-discuss_lists.opensource.org/2011-December/017416.html)

I recommend you either change the license type, and pick a license that only allows research usage, or use the `Apache 2.0 License` without the `only for research` restriction
