support installation of MiaplPy with pip install -e (editable mode)

[falkamelung]

Hi @mirzaees ,
I tried to install MiaplPy in editable mode using pip install -e tools/MiaplPy so that there is no need to specify PATH and PYTHONPATH. This works for me for MintPy but it does not for MiaplPy ( I always need to say export PATH=${PATH}:${MIAPLPY_HOME}/src/miaplpy ). ChatGPT tells me that some declaration in the PyToml or setup.py is missing. It tells me that

entry_points={
    'console_scripts': [
        'miaplpyApp = miaplpy.miaplpyApp:main',
    ],
}

needs to be added to the setup.py. I did not try this, but something to consider to make the code more robust.
