[reportlab-users] Deprecated warning on Python 3.10

[Frank Epperlein]

Hi all,

I have a deprecation warning using Python 3.10+.

It was already mentioned by someone else over here: https://groups.google.com/g/reportlab-users/c/neGnrnTsZ9g

The warning I get when importing the module using Python3.10 is reproducible like this:

> $ python3.10 -Wall
> Python 3.10.12 (main, Jun 11 2023, 05:26:28) [GCC 11.4.0] on linux
> Type "help", "copyright", "credits" or "license" for more information.
> >>> import reportlab
> <frozen importlib._bootstrap>:283: DeprecationWarning: the load_module() method is deprecated and slated for removal in Python 3.12; use exec_module() instead



Anyhow, now that I see it myself I made a small patch to update the relevant code part.

Please consider updating the package, before Python 3.12 gets released later this year.

Thank you
