Custom & Auto Quantization, Job Cancellation, and Project Folder Creation

🚀 New Features

Custom & Auto Quantization Support

• Introduced flexible quantization configuration options:
  • Users can manually define bitwidth, symmetry, per-channel settings, and rounding behavior.
  • Alternatively, automatic quantization selects optimal settings based on calibration data.

Quantizer Module Added

• Added a new quantizer module and corresponding launcher client API, enabling quantization workflows to be run through PyNetsPresso's unified interface.

Benchmark & Conversion Task Cancellation

• Users can now cancel benchmark and conversion tasks in progress, offering greater control during long-running operations.

Automatic Project Folder Creation

• When launching tasks, a project folder is now created automatically if one doesn’t exist, organizing output files consistently.

JWT Expiration Handling Improvement

• A 60-second buffer has been added to JWT token expiration checks to prevent unintentional session timeouts.

🐞 Bug Fixes

• Added InternalServerError exception to clearly distinguish server-side failures from user errors.

🧠 Why these matter

• These updates significantly improve the flexibility and robustness of the optimization pipeline.
• Quantization is now easier to configure or automate depending on user preference and hardware constraints.
• Automatic folder creation and cancellation support improve user experience, especially during iterative workflows.
• Better token handling and error classification reduce friction and simplify debugging.
