[c++] How can I get a list of vehicle_part at a grid location from a tripoint?

Stuck on my fix for #22764

I can't figure out how to get a list of vehicle_part from a grid location.

Describe the solution you'd like

I'm happy to build a function that will do this for other people, if I have some way to get a list of everything (or a partial list of some things) at a grid location.

I found how to get a list of vehicles, but that's going to give me all parts in that vehicle, not all parts on the specific grid space

Describe alternatives you've considered

if the vehicle object will let me query a given part from either a tripoint or an local offset that I can derive from said tripoint+[some property listing vehicle's origin for the offset] I could probably make that work

Additional context

22764 has more cogent examples and lists some of the actual code pages

vehicle_part appears to be the actual type for vehicle parts, it's found in src/vehicle_part.cpp a list of vehicles can be gathered using this: VehicleList vehicles = get_vehicles(position,position) found in src/map.cpp

I can't test or verify that this is correct, but it looks like maybe you want map::veh_at and optional_vpartposition::[avail]part_with_feature using the flags in veh_type.h to construct something like

here.veh_at( target->pos() ).part_with_feature( VPFLAG_SEATBELT , true ); // or
here.veh_at( target->pos() ).avail_part_with_feature( VPFLAG_SEATBELT ); // maybe?

in mattack::ranged_pull with an if statement and whatever other logic, obviously

Ty, I'll review that and if it does what I need I'll close this
