Add do_snap parameter to PMP::autorefine_triangle_soup

[LeoValque]

Summary of Changes

The PR adds the do_snap parameter to autorefine_triangle_soup(). When set to true, the coordinates are rounded to fit in double with additional subdivisions, preventing any self-intersections from occurring.

What do you think of apply_iterative_snap_rounding() ? cc @MaelRL

[LeoValque]

do you suggest to create a new function apply_iterative_snap_rounding() or simply to rename the parameter do_snap to apply_iterative_snap_rounding ?

renaming the named parameter, provided Mael thinks it is a better name too.

I do not like an apply_ prefix. Did you have a look at the existing function for 2D

note that's a named parameter, not a free function

there is already the named parameter : apply_per_connected_component()

OK, but I also meant the function snap_polygon_soup(): even if it's internal, best to still avoid naming similarities.

for that one it could be internal::polygon_soup_snap_rounding()

[afabri]

Isn't this a breaking change?

[LeoValque]

@sloriot If I understood correctly, the recommendation to the user is to have their visitor inherit from Default_visitor. If this is done, it is not a breaking change.

[afabri]

@sloriot is that something of general interest and should go in number_utils or similar?
