Enhanced upload and download speed configurations and optimizations

[Dev-Yoko]

✨ Enhance upload speed calculation and optimization

✨ Modify the progress_bar function to dynamically calculate upload speed based on actual progress and elapsed time, providing a more accurate representation of upload speed.

🛠️ Review and test the code thoroughly to ensure optimal performance and reliability.

ℹ️ I have not tested this code myself. My conclusion is that this code will work, but thorough testing is recommended.

ℹ️ Enhance download speed configuration

ℹ️ Modify aria2_Download function to optimize download speed parameters:

• Increase the number of connections to 32 for parallel downloading
• Limit maximum download speed to 10 MB/s to prevent network congestion
• Maintain seed time as 0 and summary interval as 1 for real-time status updates
• Adjust other parameters for improved performance and stability

🔧 Adjust values according to network conditions and requirements.

🛠️ Review and test changes thoroughly before deployment.

@Dev-Yoko Thank you for the PR and a detailed review of your changes. can you please test it once by yourself ? that will be convenient as it is going to be used by lot of people.
Also, it is necessary to limit the download speed in aria2 ? Last time I saw, aria2 only supported 16 connections maximum
