Maximum-J Objective

[dpanici]

With the bounce averaging and bounce point finding utilities, it should be possible to do max-J optimization like is done recently by Goodman, also relevant paper by Rodriguez

[rahulgaur104]

Max J optimization usually works by taking the derivatives of J which end up being bounce averages of cvdrift and gbdrift as done in the bounce average shifted circle test.

Two separate implementations: one for Equilibrium and OmnigenousField

Could be useful to have just plotting functionality for J initially
