Edit Json output

[Cactustory]

Hello
I need to add way_id to json output.
I edited car.lua to have way_id( result.way_id = way:id()). I dont know if its correct or not.
Now how can I add it json output?

function process_way(profile, way, result, relations)
-- the intial filtering of ways based on presence of tags
-- affects processing times significantly, because all ways
-- have to be checked.
-- to increase performance, prefetching and intial tag check
-- is done in directly instead of via a handler.

-- in general we should try to abort as soon as
-- possible if the way is not routable, to avoid doing
-- unnecessary work. this implies we should check things that
-- commonly forbids access early, and handle edge cases later.

-- data table for storing intermediate values during processing
local data = {
-- prefetch tags
highway = way:get_value_by_key('highway'),
bridge = way:get_value_by_key('bridge'),
route = way:get_value_by_key('route')
}
result.way_id = way:id()

-- perform an quick initial check and abort if the way is
-- obviously not routable.
-- highway or route tags must be in data table, bridge is optional
if (not data.highway or data.highway == '') and
(not data.route or data.route == '')
then
return
end

The "usual" workaround for this is to embed the way id in the name in order to be able to get it back in output, see #5707 (comment).
