WIP: Windows support

[contsili]

With these changes I can run pcntoolkit on windows, we still need to discuss if we want to go forward with that and also test again if this branch works fine in Unix too.

Checks:

• All the tests pass locally
• The first 4 examples (example00 to example03) on the examples/ folder (same as the ones in the websire) run successfully.
• Example04 runs fine but after fit predict finishes it gives the warning:

 c:\Users\kontsi\AppData\Local\anaconda3\envs\.ptk-dev\Lib\site-packages\dask\_task_spec.py:768: RuntimeWarning: invalid value encountered in sqrt
  return self.func(*new_argspec)

• the rest of the examples i have not run yet

[contsili]

After discussion with the team, we decided that Windows support is very low priority, so it won't be implemented.

The main reasons are:

1. Simply the userbase has not asked much for windows support
2. It is better for @contsili to develop in a linux/mac enviroment to be able to understand better the issues from the userbase
3. Windows might have issues with the BLAS (pymc library)** when running HBR model. This might make the process slower.
4. Windows need more packages to be installed (see make, and m2w64 c++ compilers)
5. If we support windows we need to test always every release on it adding time

** The error related to BLAS that appears in Windows and not Linux:

c:\Users\kontsi\AppData\Local\anaconda3\envs\test-ptk-dev\Lib\site-packages\pytensor\link\c\cmodule.py:2986: UserWarning: PyTensor could not link to a BLAS installation. Operations that might benefit from BLAS will be severely degraded.
This usually happens when PyTensor is installed via pip. We recommend it be installed via conda/mamba/pixi instead.
Alternatively, you can use an experimental backend such as Numba or JAX that perform their own BLAS optimizations, by setting pytensor.config.mode == 'NUMBA' or passing mode='NUMBA' when compiling a PyTensor function.
