Expose more parameters for CLI

[ZedongPeng]

Description

Some internal solver parameters are currently hard-coded or not exposed in the CLI, such as

• int l_inf_ruiz_iterations;
• bool has_pock_chambolle_alpha;
• double pock_chambolle_alpha;
• max_iteration in estimate_maximum_singular_value

These options will allow users to better tune the solver for large or difficult problems.
