This PR introduces significant updates to the PicoSDK Python wrappers, focusing on expanding functionality for PS4000A and PS3000A devices and improving data handling.

New Features & Utilities

  • Added many new methods to Device and Library classes to expose more device capabilities.
  • Implemented SingletonScopeDataDict class to improve scope data management.
  • Added automatic argument conversion to correct C types to reduce type-related errors.

Device-Specific Updates

  • PS4000A (ps4000a.py): Renamed functions to follow snake_case convention and corrected the PICO_CHANNEL variable definitions.
  • PS3000A (ps3000a.py): Added missing enumerations to support full device functionality.

Bug Fixes

  • Fixed the make_symbol method in the Library class to correctly generate snake_case methods (handling of _ prefixes).
