Hardware-accelerated DHT22 library using the RP2040 PIO coprocessor.
Offloads the entire DHT22 protocol (wake-up pulse, handshake, and 40-bit data capture) to the RP2040's PIO state machine. Fully non-blocking, async-friendly design with checksum validation, structured error states, and runtime pin switching. Zero bit-banging, zero delayMicroseconds, zero interrupts.
