When creating a dummytable, the warning is emitted:
DeprecationWarning: Seeding based on hashing is deprecated since Python 3.9 and will be removed in a subsequent version. The only supported seed types are: None, int, float, str, bytes, and bytearray.
Furthermore, when using the same code on 3.11 or 3.12, I get this error instead:

Expected behavior
The dummytable should be created with no warning or error.
Scenario for reprodution
Reproducible test case
Please provide a minimal, reproducible code sample, a copy-pastable example if possible:
I haven't been able to make one yet, but changing this in the installed copy of petl in my .venv folder resolves the warning.
Version and installation information
Please provide the following:
Value of petl.__version__: 1.7.14
Version information for any third-party package dependencies that are relevant
Version of Python interpreter: 3.10
Operating system (Linux/Windows/Mac): Linux Pop!_OS 22.04 LTS
How petl was installed (e.g., "using pip into virtual environment", or "using conda"): uv pip install .venv
Also, if you think it might be relevant, please provide the output from pip freeze or
conda env export depending on which was used to install petl.
Additional context

Also, feel free to remove all sections and text that aren't relevant.
