Patch size grid artifact in segmentation mask output

[derekthirstrup]

Megaseg model patch size edges not being blended so grid artifacts present in output masks.

How important is this feature to you? (Software team will re-prioritize all tickets based on current workload)
high priority bug since it introduces artifacts in structure segmentation mask.

Describe the solution you'd like
Easiest thing would be to make a checkbox to set the patch size to the whole fov xyz dims so these artifacts go away. Could also work on optimizing the fusing/blending of edge overlap areas so that output segmentation masks don't have these artifacts.
