Simplify / document antimony import

[dweindl]

• Wrapper for importing antimony models, this will allow for more concise test cases in the future
• Remove tellurium dependency, use libantimony directly (so we don't need ncurses and other deps)
• Add antimony example

nice! does it make sense to also enable petab import for antimony?

does it make sense to also enable petab import for antimony?

At least for now, I would not do that. Antimony<->SBML interconversion is rather lossless and fast, so I don't think there is much of an advantage to support antimony directly with PEtab. I would still default to SBML in PEtab unless there is compelling reason to use something else. If there is a request backed by sufficiently many users, we could add it at some point, though.
