Add Threads parameter to control parallel driver download throttling

Browse Source 
Introduces a new `Threads` parameter that allows users to configure the concurrency level for parallel driver downloads within the script. This parameter defaults to 5, matching the existing UI behavior, and accepts values between 1 and 64 to provide flexible control over resource utilization.

The parameter is now passed to the parallel processing function via the `ThrottleLimit` argument, enabling users to optimize performance based on their system capabilities and network conditions.
