fix layout of textplot_network

[fkrauer]

Hi

I am plotting the co-occurences with textplot_network(). Is there a way to fix the layout of the network (the position of the nodes) so that it is reproducible every time I run it? I already set.seed(), but the layout still changes.

Bw, Fabienne

PS: using quanteda 1_4_3 (yes I know, I should update)
