The GL_EXT_unpack_subimage and GL_EXT_texture_rg are part of the core ES 3.0 specification, so also check the GL driver version in addition to the extension string to determine if those features are supported.
This allows using those extensions on some GL drivers that do not expose them in the extensions string, but still support OpenGLES3.
