abstract: Bindings to 'Uno' (Unifying Nonlinear Optimization), a C++ solver for smooth
  nonlinearly constrained optimization. 'Uno' unifies Lagrange-Newton methods, including
  sequential quadratic programming and interior-point methods, by decomposing them
  into interacting building blocks (constraint-relaxation, inequality-handling, Hessian,
  and globalization strategies) that can be freely combined, either through options
  or through presets that reproduce established solvers such as 'filterSQP' and 'IPOPT'.
  The framework is described in Vanaret and Leyffer (2024) <https://doi.org/10.48550/arXiv.2406.13454>.
