Add A* Implementation Back to GIO

[GoldinGuy]

Goal: Sometimes Gold Star finds distances that are biologically infeasible - let's traverse through the mask to find the shortest distance

Problem: Masks have holes in them around landmarks of interest

Possible solutions:

• Use masks without holes in them
• Fill in holes using (insert ML, blob, identify where particles are using x,y csv and then filling in mask respectively)
• Something else!
