dr_tf_inboard inconsistent

[clmould]

Description

Closes #3574
ixc=13 and ixc=140 cannot be used simultaneously. Added a warning when both these iteration variables are being used in an input file. Removed ixc=13 from any input file that also has ixc=140 being used. Fixed a small error in the docs.

Happy with code changes. Going to ask @chris-ashe to check he's happy with the diffs and that removing ixc 140 is the best one to remove and not 13.

Having dr_tf_inboard as an iteration variable should generally not be a thing as it is the summation of 3 other variables that can be iterations. For the sake of convergence dr_tf_wp should be set as an iteration to allow for sizing of the winding pack based on the superconducting constraints.
