NF: Add lazy_loader feature in FURY

[WassCodeur]

This pull request introduces the lazy_loader feature to optimize module loading in the FURY . Lazy loading improves performance by deferring the loading of modules until they are actually needed, thus reducing startup times and memory footprint.

Changes included in this PR:

• Implementation of lazy loading across multiple modules in FURY.
• Updated __init__.py files to support lazy loading where necessary.
• Added type stubs (__init__.pyi) to provide type indications for lazy loading modules.
• Improved module organization and structure to effectively support lazy loading.

This feature aims to improve the user experience by speeding up application start-up and improving overall performance in scenarios where not all modules are immediately required.

Thank you for this. Can you rebase ?

Hi @WassCodeur , why does this have the keyword decorator commit?
Also, I believe you should have a look at the lazy loading implementation in Scikit-Image.
You will have to make changes in pyproject.toml

Hi @deka27!
Thank you. By the way, I had created the lazy_loader branch from the keyword_only branch. Thanks a lot for the reminder to update the pyproject.toml.

Okay, I understand. I feel you could have implemented as a new feature branch only (it will be tough to review both features at once, so u might need to rebase properly).
Also u might need py.typed file (this is so that type_stub files are compiled properly).

[WassCodeur]

Okay, thanks a lot @deka27 . I'll look into integrating py.typed.

Hi @WassCodeur,

Thank you for this! I tried and it works like a charm. I compared performance using python -X importtime -c "import fury; import fury.lib" 2>import.log and I see improvement so it is ready to go.
