Issue with SDK > 31 on Android 12

Looks like it does not request the permission correctly on Android 12.
You might be able to fix it like this
This is on line 155 on file SerialPortBuilder.java
//PendingIntent mPendingIntent = PendingIntent.getBroadcast(context, 0, new Intent(ACTION_USB_PERMISSION), 0);
PendingIntent mPendingIntent = null;
if(android.os.Build.VERSION.SDK_INT >= 31) {
mPendingIntent = PendingIntent.getBroadcast(context, 0, new Intent(ACTION_USB_PERMISSION), PendingIntent.FLAG_IMMUTABLE);
} else {
mPendingIntent = PendingIntent.getBroadcast(context, 0, new Intent(ACTION_USB_PERMISSION), 0);
}

Unfortunately I am having trouble to build the library so I cannot really test it.
I am quite happy to confirm if it works if someone explain how to build the lib

I have managed to recompile the library and it works
however I have had to add the following dependency for lib serial to work
implementation 'com.squareup.okio:okio:3.3.0'
