Update to v0.6.2 of the underlying PIQP library
Migrate from R6 to S7 OOP system
Inequality constraints are now double-sided: h_l <= Gx <= h_u
Variable bounds renamed: x_lb/x_ub to x_l/x_u
Result fields renamed: z to z_l/z_u, z_lb/z_ub to z_bl/z_bu, s to s_l/s_u, s_lb/s_ub to s_bl/s_bu
Info fields renamed: primal_inf to primal_res, dual_inf to dual_res
New settings: infeasibility_threshold, preconditioner_reuse_on_update
Use generic functions solve(), update(), get_settings(), get_dims(), and update_settings() instead of R6 methods
Support for problem data updates and warm starts via update()
