Description: 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)
    <doi:10.48550/arXiv.2406.13454>.
