Damask-parse

Changed

- Include the `orientation_coordinate_system` (e.g. `{'x': 'RD', 'y': 'TD', 'z': 'ND'}`) in `validate_orientations`.

Changed

- Support `stress_rate` (i.e. `dot_P`) in `write_load_case`.

Changed

- Update `ParticleDistribution` so a perpendicular vector is calculated for either of `major_axis_direction` or `major_plane_normal_direction` if only one of these is specified.

Changed

- Add class `particles.ParticleDistribution`, and allow multiple distributions to be added to a `particles.ParticleRVE`.

Added

- Add class `particles.ParticleRVE` and function `particles.generate_particle_distribution` for generating RVEs with particles.

Changed

- The orientations dict must now include a key `quat_component_ordering` if specifying quaternion orientations, with a value "scalar-vector" or "vector-scalar".

Fixed

- Fix issue where `np.longdouble`-precision quaternions do not maintain that precision due to arithemtic with lower-precision data.

Changed

- Only include in the `material.yaml` file the phase definitions of used phases.
