Requirements disabled in setup.py

[EiffL]

I'm installing the WeakLensingDeblending package on a bare system, and was surprised to have to install dependencies that weren't automatically grabbed by the setup.py.

It looks like the install requirements is commented out:

WeakLensingDeblending/setup.py

Line 30 in edab9bc

install_requires=[ ], #requirements,

Is there a reason for that? If it's because there are some packages that can be annoying to install, it's possible to define several install configurations, and I can set that up. For instance, having the default not try to install galsim or something like that

This is a really bare bones setup.py since this code has mostly been used as an application rather than a library, and any modernization is definitely welcome. When we started this, galsim was not pip/conda installable but now I don't see any reason not expose the full set of requirements.
