This program is only tested on Debain using IOS 15. But it should also work on other Linux distributions and IOS versions.
Windows will be supported soon, get the libimobiledevice binaries from here
Note for IOS 16: The program requires the activation of IOS Developer Mode.

Install python3, git, python3-pip and python3-tk with your favourite package manager (here: names for apt)
Install missing python modules:

pip install Pillow geotiler

Download and run the program:
With git:

git clone https://github.com/lasnikprogram/ios-location-changer && cd ios-location-changer
python3 main.py

Without git:

wget https://github.com/lasnikprogram/ios-location-changer/archive/main.tar.gz
tar xf main.tar.gz
rm main.tar.gz
mv ios-location-changer-main ios-location-changer
cd ios-location-changer
python3 main.py

Connect your IOS device, the program will automatically try to install and mount a developer disk image to change the location of the device to the marker present on the map.
