Python 3.9 compatibility

[ZJaume]

Is Python 3.9 going to be supported? When I try to install from source with a lower Python version it says it only supports Python <3.12 >=3.9. But then, installing it and running with Python 3.9 it seems that there are some idioms that are from higher versions and the interface crashes like:

python -m text_dedup.simhash -h

Traceback (most recent call last):
  File "/usr/lib/python3.9/runpy.py", line 188, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)
  File "/usr/lib/python3.9/runpy.py", line 158, in _get_module_details
    code = loader.get_code(mod_name)

  File "/work/user/text-dedup/text_dedup/minhash.py", line 170
    match args.hash_func:
          ^

python -m text_dedup.minhash -h

It would be helpful to have the option to run at least with python 3.9 or even 3.8. 3.10 is still too new and it's not available in some environments and sometimes the user does not have a choice.

Thanks for pointing this out; I have updated the requirements. Unfortunately, Python 3.9 or lower will not be supported at this moment due to limited bandwidth. However, feel free to fork the repo and change the syntax to your needs or use a virtual Python environment.

Alright, thanks!
