- Implemented a comprehensive test script (test_micropython_pico.mjs) that performs the following:
- Part 1: Checks backend compilation of a simple Arduino sketch for the rp2040:rp2040:rpipico board.
- Part 2: Downloads MicroPython v1.20.0 UF2 firmware and loads it into a rp2040js simulator.
- Part 3: Simulates the Pico, verifies REPL output, and checks execution of injected Python code.
- Includes detailed logging and error handling for each step of the process.
