Comma separated string in tag causes panic

[kbumsik]

Setting "0,1,2,3" for tags causes pinc.

For example,

pyroscope.configure(
    application_name="Test",
    server_address="http://localhost:4040",
    detect_subprocesses=True,
    oncpu=True,
    gil_only=False,
    tags={
        "slurm_step_gpus": "0,1,2,3",
    },
)

I got the following error:
