[BUG] The new rust version again falls for the same out of memory errors

[amir16yp]

Describe the bug Runs out of memory when computing large maps. I think its the same as #8 except the problem is in rust. The solution would be to use memory-map files to store data instead of memory like i did in the python version in PR #30   Used bbox parameter 34.549942,31.490310,34.651909,31.570931

Additional context Issue does not occur in the python version
