Choosing a max Delaunay distance

[rbutleriii]

I noticed that the tutorials select particular distances for the maximum_distance_delaunay setting (e.g. 50 for the CosMx vs 400 for the Seqfishes), but the current function has an auto setting. Does that basically choose the best setting? In the papers it showed the graphs for plotStatDelaunayNetwork but I didn't find a description of how to make that deterrmination.

Passing auto for this param means that the max network distance allowed will be automatically set as the largest delaunay distance that is not deemed an outlier. This maximal value is determined using the 5th value of grDevices::boxplot.statsboxplot.stats(), and should usually produce a reasonable max distance.

This documentation is present in the more specific createSpatialDelaunayNetwork(), but we should add it to createSpatialNetwork()
