libdaisy v8.0.0 Update & Cosmolab Board Support

[fmulassano]

Hi maintainers,

I've created a Pull Request that updates Oopsy to libdaisy v8.0.0 and adds support for the Cosmolab board by Faselunare.

What's Included

• libdaisy v8.0.0 Compatibility: All breaking changes from the v8.0.0 migration guide have been addressed

  • GPIO/Pin migration (dsy_gpio → GPIO class)
  • UartHandler API migration (DMA listen mode)
  • Hardware structure updates (seed → som)
  • System API updates

• Cosmolab Board Support: Full support for the Cosmolab board featuring:

  • 32 pads (4x8 matrix) via CD4021 shift registers
  • 8 multiplexed knobs via CD4051
  • 48 RGB LEDs via PCA9685 drivers
  • OLED display support
  • MIDI input/output
  • 4 CV inputs, 2 CV outputs
  • Gate input and output

• Documentation: Comprehensive changelog added to README.md explaining all changes and migration notes

Testing

The PR has been tested and compiles successfully. All examples work correctly with libdaisy v8.0.0.

Important: After merging, users will need to run ./install.sh to rebuild libdaisy with the new APIs.
