Install fails on python 3.14

[jmrohwer]

When trying to install on Linux using pip in a clean environment under Python 3.14, the install fails due to the "fastobo<0.14" dependency. Because no wheel is available, pip builds fastobo from source but fails due to PyO3 not supporting Python 3.14 (this is trying to build fastobo 0.13.0):

        error: the configured Python interpreter version (3.14) is newer than PyO3's maximum supported version (3.13)
        = help: please check if an updated version of PyO3 is available. Current version: 0.23.4
        = help: set PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1 to suppress this check and build anyway using the stable ABI

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

Is Python 3.14 not supported?

@jmrohwer fastobo>0.14 should fix this and has support for 3.14

https://pypi.org/project/fastobo/

So why the "fastobo>=0.13.0,<0.14" dependency in pyproject.toml?
