support for RPI Pico W

[nordseele]

Hi, I'm testing ArduinoOSC on a Raspberry Pico W (w/ Arduino-Pico from Earl Philhower https://github.com/earlephilhower/arduino-pico) after quickly editing ArduinoOSCWiFi.h and adding the Pico platform to it:

defined(PICO_RP2040)

#if defined(ESP_PLATFORM) || defined(ESP8266) || defined(ARDUINO_AVR_UNO_WIFI_REV2) || defined(ARDUINO_SAMD_MKRWIFI1010) || defined(ARDUINO_SAMD_MKRVIDOR4000) || defined(ARDUINO_SAMD_MKR1000) || defined(ARDUINO_SAMD_NANO_33_IOT) || defined(PICO_RP2040)
#define ARDUINOOSC_ENABLE_WIFI
#endif

[...]


#elif defined(PICO_RP2040)
#include <WiFi.h>
#include <WiFiUdp.h>

It's kind of a dirty hack but I wanted to try your library. And it seems to work just fine. I'm not sure yet if there's anything else that needs to be modified to add full support for this board.

It's worth noting that I'm getting a compiler warning/error though (posted below). But I'm not sure it's totally related to ArduinoOSC yet.

defined(PICO_RP2040) is the only "define" I could find in the Pico SDK, I'm not familiar with these, perhaps there's a Define specific to identify the RPI Pico W (wifi). The cyw43 maybe.

I'm happy to test in depth with the Pico W and to add more details if you'd like to add official support for it.

Best,

Edit: I've removed a question from my first post about OSC pattern matching notation. Both the { } and [ ]methods are confirmed working using your library. I was just misusing the curly braces notation, it's fixed now.
