Adds extra radar description to see how much time it should take to scan, at full power.

Applies to all radars. If you have a radar that should not look like a radar, let me know and I will skip applying to those, or you can do a thing like this, in data-final-fixes:
if mods["radar-time"] then
radar_time_excluded_names = radar_time_excluded_names or {}
--[name] = true the radar names
end

which may be messy... or just ask me and I can probably figure out an option.
