Allowing different multiprocessing engines

[orellabac]

**Is your feature request related to a problem? Please describe
I hace environments were I cannot use this library because i cannot leverage multiprocessing only threading.

Describe the solution you'd like
Using a backed that allow multiple backends will be great

Describe alternatives you've considered
Joblib

Hi @Wittline do you think it will possible to consider this change ?

Hi @sfc-gh-mrojas could you please provide more technical details? I did not see your requests before, I am not receiving notifications about new issues.

[sfc-gh-mrojas]

Sure. Currently the code depends on the multiprocessing lib. The problem is that in some environments I cannot spawn new processes. I think there is PR using job lib that way the backend is configurable and it allows several scenarios. We would like to allow that.
What are your thoughts?

Hi @sfc-gh-mrojas @orellabac, have you had a chance to test the performance of the code? If so, could you please share some details about the performance with different sizes of CSV files?

I would be interested in knowing the processing time and memory consumption for files of varying sizes. It would also be helpful to understand if there were any particular bottlenecks or challenges that you encountered during your testing.

Any additional insights you can provide on the performance of the code would be greatly appreciated. Thank you!
