Add RP2040 oscilloscope device support

This PR adds support in OpenHantek for an RP2040-based oscilloscope implementing the OpenHantek6022 protocol.

Firmware repository:
https://github.com/dgatf/oscilloscope_rp2040

Included changes:

  • new RP2040 device model
  • RP2040 calibration file
  • device detection / USB handling updates
  • udev and devd rule updates

The firmware provides a 2-channel oscilloscope compatible with the OpenHantek protocol.
In current testing, capture is reliable at 500 kS/s. Higher nominal sampling rates are available, but may drop samples depending on the configuration and USB transfer limits.

This PR only contains the OpenHantek-side changes required for RP2040 device support.
