Periodic Boundary Conditions

[william-silversmith]

Hi,

It means that D(x)=D(x+L), where L is the length of the box along x, so that in the following case:

data = np.array([[3,3,0,3,3]])
labels_out = cc3d.connected_components(data, connectivity=6)

Thereby instead of array([[1,1,0,2,2]], dtype=unit16) it will output array([[1,1,0,1,1]], dtype=unit16) if periodic boundary condition is applied.
Maybe this wiki would be helpful in explaining what I meant.

A simple solution could be to post-process the labels at the boundaries after labelling.

Done! Added 4 and 6 connected support to 3.13.0

Great! Thank you!
