torch_facing_direction is opposite the actual facing direction for horizontal faces

All torches have a `torch_facing_direction` property.

As according to the wiki, these values can be `north`, `south`, `east`, `west`, and `up`.

Going by the name (facing) you would be excused for thinking that east means the torch faces east, but no! it actually faces west. `west` actually means an east-facing torch, and north/south are similarly the wrong way round.

I recently encountered this during a custom server's development.
