Add get_h(), which automagically produces the inequality matrix

Reduce the max values for main stat, power and defense
to reflect non-use of datacrons and stims.

Add a first attempt at the get_h() function.
This will generate all combinations of stat restrictions
for the inequality matrix to be passed to sqp().

Currently has restrictions for 2 secondary stats,
expertise,
and main + secondary stat.

Yet to be tested.
