Writing ε and Γ_c compute funs with new methods

[unalmis]

This PR adds new compute functions for Gamma_c and effective ripple using the numerical methods in #1119.

• Write compute funs (rename old ones by prepnding * to the compute quantity name)
• Compare results to Effective ripple ε #1003 and Gamma_c (Nemov and Velasco et. al) Γ_c #1042
  • Matches Neo better than DESC's previous than spline implementation, except near axis where both desc implementation agree and differ from neo
• Write new objectives (rename old as above)

Notes

I won't get to this until next week. If someone needs this before then, feel free to try out. Basically the compute function will no longer have source grid requirement, just grid requirement = meshgrid then use Bounce2D as in the examples in test/integrals on #1119.
