Placing farming seeds doesn't work

[scr267]

Hi, placing farming seeds don't seem to work due to positioning requirements by the farming mod.

at https://github.com/mt-historical/lwscratch/blob/bfeeb6cc962a09a4a6951018a7a9172e40f8a011/robot_ops.lua#L480C1-L485C5

	if stack:get_name ():sub (1, 8) == "farming:" then
		pointed_thing.under = { x = place_pos.x + vec.x,
										y = place_pos.y + vec.y,
										z = place_pos.z + vec.z }
		pointed_thing.above = place_pos
	end

line 482 should become;

y = place_pos.y + vec.y - 1,

It works on my local build with this modification.
