[doctormee]

Description

Add upper bounds for Lipschitz constants / precision of calculations, return those estimates.

Also need to estimate structural stability threshold (p)

• [x] A^* in get_support_set for no trading constraints
• [ ] A^* in general
• [ ] Lipschitz for Constraints support function (in precalc/get_support_set)
