Enhance dynamic range logic

[afischerdev]

This is a follow up for PR #729
It fixes the new logic described here

And for the car profiles an activation is possible for track and road in “Dynamic Range Mode”.

@abdullahO2
As before the results are availabe on testserver.

New logic for the waypoints finding when using dynamic range:
Waypoints that starts or ends in an island exception. Please see example

@abdullahO2
The new library is now available on the test server.

@afischerdev

Thank you for the update! I've been testing the new library on the test server, and the results are truly impressive. The new dynamic range logic is working remarkably well.

However, I've noticed significant slowdowns in some cases, eventually leading to a complete loss of server response. I encountered a "java.lang.OutOfMemoryError: Java heap space" error similar to the one reported previously (see link below).

Here are a couple of examples where I experienced the slowdowns before the server stopped responding:

• https://brouter.de/brouter-test/#map=8/18.436/45.675/standard&lonlats=46.720379,22.287226;46.604144,18.122351
• https://brouter.de/brouter-test/#map=8/22.159/48.235/standard&lonlats=48.103582,23.083552;48.806759,20.956385

#729 (comment)

I suspect that the slowdowns and the OutOfMemoryError might be related to enabling the highway=track mapping along with the dynamic range, as I noticed similar behavior before the latest changes. Could you please investigate this further? In the meantime, I'll continue testing when the server is back online.

@abdullahO2
I've started the test server again.

Hard to say what happens. I have no idea.
I made a local stress test with the test server start parameter and your two requests and a hundred runs from different threads - no abnormalities.

Thank you for restarting the test server!

I've been testing the latest version extensively, and I haven't encountered any other significant issues. The dynamic range feature is working exceptionally well, and I'm very happy with the results.

Thank you again for all your hard work and dedication to this feature. It's truly made a huge difference!
