v0.12.2

What's Changed

• Add Vector Potential Calculation to Coil classes and Most MagneticField Classes
• Add automatic intersection checking to CoilSet objects, and a method is_self_intersecting which check if the coils in the CoilSet intersect one another.
• Add flip_theta compatibility function to switch the zero-point of the poloidal angle between the inboard/outboard side of the plasma.
• Change field line integration to use diffrax package instead of the deprecated jax.experimental.odeint function, allowing for specifying the integration method, the step-size used, and more. See the documentation of field_line_integrate and diffrax for more details.
• Add use_signed_distance keyword to PlasmaVesselDistance objective to allow for specifying the desired relative position of the plasma and surface.
• Vectorize Boozer transform over multiple surfaces, to allow for calculation of Boozer-related quantities on grids that contain multiple radial surfaces.
• Optimizer now automatically scales linearly-constrained optimization parameters to be of roughly the same magnitude, to improve optimization when parameter values range many orders of magnitude
• Add HermiteSplineProfile class, which allows for profile derivative information to be specified along with profile value information.
• Add installation instructions for RAVEN cluster at IPP to the docs
• Change optimizer printed output to be easier to read
• Add HeatingPower and FusionPower objectives
• Reduce QuadratureGrid number of radial points to match its intended functionality
• Fix some plotting issues that arose when NFP differs from 1 for objects, or when passed-in phi exceeds 2pi/nfp
• Update VMECIO to allow specification of Nyquist spectrum and fix some bugs with asymmetric wout files
• The code no longer mods non-periodic angles (such as the field line label $\alpha$) by $2\pi$, as in field-line-following contexts, functions may not be periodic in these angles.
