conan error when trying to install proposal on Ubuntu 20.04/22.04

[sjoerd-bouma]

Since yesterday, it seems pip install proposal==7.5.0 fails during wheel building with the error RuntimeError: conan was not able to create a new profile named {name}. The error occurs both on my local system on Ubuntu 22.04 on a clean python 3.10 venv, as well as on the NuRadioMC CI system under both Ubuntu 20.04 and 22.04 on Python 3.7. ~I'm not sure what's causing this, as until yesterday it seemed to be fine...~ It seems conan was updated this morning - presumably either the conan commands need to be updated, or setup.py needs to be fixed to an older version of conan?

  note: This error originates from a subprocess, and is likely not a problem with pip.

Fixed this by requiring conan<2.0 on https://github.com/sjoerd-bouma/PROPOSAL, I can make a PR or someone can just implement this / upgrade to conan 2.0.

For now, the simple fixed would be to fix conan to 1.x in pyproject.toml if it is not easy to directly support conan 2

This has been fixed for now with #355, and is now tracked by #358
