New LBFGS Solvers (thanks to A. Ivanov)

Added new solvers for energy minimization LBFGS_Atlas, LBFGS_OSO and VP_OSO.
These new solvers circumvent the explicit renormalization of the spins by working with norm-preserving maps - either stereographic atlases or matrix exponentials.

Sparse HTST

Implementad a sparse version of HTST, which can be used if no dipole-dipole interactions are present. If applicable, it is much faster and more memory-efficent than the dense implementation.

Other

  • added interpolated energy contributions
  • internally, mutices are now FIFO, allowing to interact with the GUI even when there are many iterations per second
  • minor fixes for HTST
  • improved log legibility
  • small improvements of ui-web
  • more and improved documentation
  • new CLI parser
  • added simulation_n_shot to python API
  • fixed unit tests for single precision
  • optional skipping of zero padding, if periodic boundaries are used
  • fixed memory leaks in CUDA backend
  • fixed api functions energy_per_spins (thanks to P. Buhl)
  • added circular domain wall skyrmions
  • added visual filters, based on lattice cell to QT-GUI
  • optimized LLG and GNEB energy calculations by deriving them from the gradient
  • moved CI to github actions
  • fixed Hessian for dipole-dipole interaction
  • improved cmake code, especially cuda integration
