Jax-fdm

Added
- Implemented `jax_fdm.parameters` to choose optimization parameters a la carte!
- Created `parameters.EdgeForceDensityParameter`.
- Created `parameters.NodeAnchorXParameter`.
- Created `parameters.NodeAnchorYParameter`.
- Created `parameters.NodeAnchorZParameter`.
- Created `parameters.NodeLoadXParameter`.
- Created `parameters.NodeLoadYParameter`.
- Created `parameters.NodeLoadZParameter`.
- Implemented `EquilibriumStructure.nodes`.
- Implemented `EquilibriumStructure.edges`.
- Added `EquilibriumStructure.anchor_index`.
- Implemented `ParameterManager.parameters_ordered` to fix order mismatch between optimization parameters and their bounds.

Changed

- `EquilibriumModel.__call__` tasks `q`, `xyz_fixed` and `loads` as arguments.
- `FDNetwork.transform` only modifies node coordinates.
- `FDNetworkViewerArtist` shifts a node load by the maximum edge width at the node.
- `OptimizationRecorder.history` stores `q`, `xyz_fixed` and `loads`.
- `LossPlotter.plot` supports `q`, `xyz_fixed` and `loads` to be compatible with `OptimizationRecorder.history`.

Removed

Added

- Enabled the creation of animations with mesh representations of the elements of a `FDNetwork`!
- `FDNetworkViewerArtist` implements `update_*()` methods to update objects in the `Viewer`.
- `FDNetworViewerArtist` implements `add_*()` methods to add drawn objects to `Viewer`.
- `FDNetworkArtist` now stores network element collections as attributes.

Changed


Removed

- Removed `FDNetworkPlotterArtist.draw_loads()` as it is handled by parent artist class.
- Removed `FDNetworkPlotterArtist.draw_reactions()` as it is handled by parent artist class.

Added

- Implemented `SecondOrderOptimizer`, which computes the hessian of a loss function.
- Added support for the `NetwtonCG` and `LBFGSB` scipy optimizers.
- Created `NodeSegmentGoal`
- Implemented `closest_point_on_segment` using `lax.cond`

Changed
