Adds compatibility for Deeper and Darker.

With Deeper and Darker installed, you'll be able to craft a stile with the Echo and Bloom wood types. Without Deeper and Darker installed, this version will behave identically to v1.1.2.

I'll push this update to 1.21.2-1.21.4 once Deeper and Darker updates. For now, 1.21(.1) only.
