Add additional constraint variables to output

At the moment only the info below is outputted to MFILE.DAT. The example below is from large_tokamak

• 🐛 All of the constraints are shown to be equality constraints
• The value of the constraint value should be output
• The value of the non normalised residual should be output
• An output to determine if the constraint is $\le$ or $\ge$
