[1.12.2] Add support for TerraFirmaCraft please

[Dragnier]

Since it is now available for 1.12.2, it would be nice to have TFC support for your mod to make it easier to put things together like TFC + Thaumcraft, TFC + Astral Sorcery, TFC + Immersive Engineering, etc.

TFC is available for 1.18.2 as well and is getting ported to 1.20.1 as well
