photonlibpy: License under MIT (#1700)

Everything under the `photon-lib` directory is intended to all be
licensed under MIT:


https://github.com/PhotonVision/photonvision/blob/e40c8fbca08e8397e00e35f72809ac69d752ad57/photon-lib/.styleguide-license#L2

Presumably we don't want to force teams to release their robot code
under GPL.
