[python] importing requests module may lead to crash

[doegox]

Just to track it down as it's probably not an easy fix...

Work fine in Bookworm docker but fails in Trixie docker:

$ cd docker/debian-13-trixie
$ ./docker_build.sh
$ ./docker_run.sh
rrg@f8e5d5626aab:~/proxmark3$ sudo apt install python3-requests
rrg@f8e5d5626aab:~/proxmark3$ make clean; make client -j
rrg@f8e5d5626aab:~/proxmark3$ echo import requests > test.py
rrg@f8e5d5626aab:~/proxmark3$ client/proxmark3 -c "script run test; script run test"
[offline|script] pm3 --> script run test
[+] executing python test.py
[+] args ''

[+] finished test

[offline|script] pm3 --> script run test
[+] executing python test.py
[+] args ''
double free or corruption (out)
Aborted

No success so far even by running scripts in some Py_NewInterpreter.
The only way it doesn't crash is by not calling Py_Finalize. Which BTW opens other perspectives as it would allow to preserve variables between script calls...

It is worth mentioning that the stack size of the Alpine image in Docker is only 80-128KB, but PM3 clients will allocate more stack space than this size at startup, leading to crashes.

So I am always very sensitive to Docker and client crashes.

It crashes on my host too (Trixie), the Docker example was just to get an easily reproducible setup.
