pybedtools does not install with python 3.13

[diekhans]

This appears to be related to changes in the Python C API

pybedtools.log

Same in Python 3.13.1

Looks like Cython 0.29.x doesn't support 3.13. Pybedtools needs to be ported.

[theAeon]

Should be fixed with 0.12.0

v0.12 now supports Python 3.13 via #424 (thanks @theAeon), and is available on PyPI and bioconda.
