Update extremePools.m

[farid-zare]

Fixing two issues with the extremePools:

1. columns were being removed except of rows
2. N was being inputed to LRS in the transposed format wrongly

• Explain why we use N = S^T,
• Describe the zero RHS and equality constraints,
• Note the check ensuring P*N' == 0 for the left null space.

Please include a short description of enhancement here

I hereby confirm that I have:

• Tested my code on my own machine
• Followed the guidelines in the Contributing Guide
• Selected develop as a target branch (top left drop-down menu)
