Python 3.13 support

EMD currently breaks on Python 3.13 as Numba does not yet support this python version: https://numba.readthedocs.io/en/stable/user/installing.html#version-support-information

EMD does install with python 3.13 and numba==0.61.0rc2 and should work with 3.13 after the next Numba release
