Dependency Upgrade Needed: Conan < 1.60.0 does not work on new linux distributions

[patrickwalton]

Describe the bug
The requirement that Conan be less than or equal to v1.59.0 makes basilisk incompatible with Fedora 38+ as described here, because Fedora 38 adopts GCC 13 and Conan doesn't support GCC 13 until v1.60.0.

I assume this will be true of other linux distributions going forward, so it's probably time to get serious about upgrading conan.

To reproduce
Steps to reproduce the behavior:

1. Install Fedora 38
2. sudo dnf update
3. Follow basilisk installation instructions. Will fail at python3 conanfile.py.

Expected behavior
Resulting error is described here.

Desktop (please complete the following information):

• OS: Fedora (but will become true of other new distributions)
• Version 38+
• Python version 3.11.4

Additional context
Workaround for now is to downgrade GCC, but since older versions aren't available through dnf install, the older version has to be built from source.

A slightly easier workaround that I have found is to edit ~/.conan/settings.yml and add "13", "13.1", "13.2" to the list of supported gcc versions.

I think this will be properly fixed in the next release. It seems like develop head only wants conan<2 not conan<=1.59 as of 2023-12-06.
