[ios] Building a long bicycle route crashes OM on iPhone 8

A route from Cologne, Germany to Poland, Hel

• iPhone 8 (16.7.7)
• Organic Maps 2024.05.10-1

This issue is likely caused by a large amount of RAM (more than 700Mb?) used by the routing engine, after that limit the system kills the app.

I'm working on profiling the app for both CPU and RAM usage, but sadly I won't be finished this week yet. I will see if I can replicate this on Android, but unfortunately can't do the same for other iPhonea, as I don't own such devices.

@Tmpod You can try profiling a desktop app, it should have a similar memory consumption pattern, as all routing is done by the same C++ code.

Yeah that's a good idea, thanks!

Some reasonable limit for the ancient devices will not hurt.
