"Abnormal" Status in Cone.find_interior_point

[natemacfadden]

Cone.find_interior_point occasionally returns the "Abnormal" status, such as in the following example:
Cone(hyperplanes=[[-400002,-400003],[-1,-1]]).find_interior_point()

The method Cone.find_interior_point() is widely used, so this bug arises in other methods, like
Cone([[-1000000.75,1000000.5], [1,-1]]).is_pointed()

This latter cone is very 'flat' (almost half-space), likely more so than in realistically encountered cones, so this may be a low urgency bug.

This also occurs semi-frequently for finding height vectors in NTFE FRSTs of 491
