Thin logs, stick layers and frost

This datapack adds thin logs, stick layers and frost.

To craft a thin log, take two logs of the same type, then put one on top of the other. Same goes for thin wood.

Note: the logs have to be mined with a pickaxe.

The datapack will announce when it has been enabled.

Functions:
Do "/function log:book" to get a control book. This allows you to move the logs and light up snow and stick layers.
"/function log:setblock/<log type>" to create a thin log. Can be used to make trees spawn with the thin logs.
"/function log:setblock/stick_layer" to create a stick layer.
"/function log:setblock/snow_partial" to create frost.
