feat: global Bridge hardcoded Serial1 dependency

 Including Arduino_BridgeImola.h gives the user access to a Bridge object that can be used both as a RPC client and/or server to execute and serve RPCs to/from the CPU Host running a GOLANG router.
 
-- The Bridge object is defined on Serial1
+- The Bridge object is pre-defined on Serial1 and automatically initialized inside the main setup()
 - The Bridge.call method is blocking and works the same as in RPClite
 - The Bridge can provide callbacks to incoming RPC requests both in a thread-unsafe and thread-safe fashion (provide & provide_safe)
 - Thread-safe methods execution is granted in the main loop thread where update_safe is called. By design users cannot access .update_safe() freely
