v0.9.2

Improvements

• Improves robustness and speed of map_coordinates.
• Adds axis parameters Ra_n and Za_n as optimizable DoF when using standard
  constrained optimization methods (ie, not ProximalProjection).
• Adds method to convert FourierRZCurve to FourierXYZCurve.
• Makes DESC classes compatible with JAX pytrees.
• Adds Chebyshev polynomials as basis function (for future use).

Breaking changes

• Renames theta_sfl to theta_PEST in compute functions to avoid confusion with
  other straight field line coordinate systems.
• Makes plotting kwargs a bit more uniform. zeta, nzeta, nphi have all been
  superceded by phi which can be an integer for equally spaced angles or a float or
  array of float to specify angles manually.

Bug fixes

• Avoids accidentally overwriting equilibria during automatic continuation method.

New Contributors

• @rahulgaur104 made their first contribution in #576
