perf_test crashes on py3.13t on MacBook M4Pro

[cboulay]

I wasn't expecting this to work, but thought I'd give it a shot anyway.

First, I had to edit pyproject.toml to requires-python = ">=3.9" and then edit the extras numpy reqs to all be at least numpy>1.24.4 (note: not >=). Then I ran the following:

uv python pin 3.13t
uv sync --extra axisarray
PYTHON_GIL=0 uv run python -m ezmsg.util.perf_test --many-dynamic-sizes

(Error occurs with-or-without PYTHON_GIL=0)

After #198, ezmsg-perf seems to run on 3.13, 3.13t (free-threaded), with/without PYTHON_GIL=0.

That's pretty neat!
